Genetics Are Not The Reason For Disease...
In this episode of Dead Doctors Don't Lie, Doctor Wallach discusses various degenerative diseases, he goes on to explain that they are not a result of genetics but instead results of mineral deficiencies. He covers Birth Defects, Type 2 Diabetes, Alzheimer's Disease, Sickle-cell Anemia, obesity and more. Doc Wallach takes calls towards the end to recommend various supplements to callers.

Autosomal and X Linked Inheritance
This lecture explains about the the autosomal and x linked inheritance. This video explains the properties of sex linked inheritance and the genetics pedigree. Autosomal trait is the one where the gene responsible for the trait is carried by Autosomes or body cell chromosomes. Sex linked trait or X linked trait is the one where the gene responsible for the trait is carried by X chromosomes. So most of the X linked trait is predominant ion male as males have only one X chromosome.

X Linked Dominant Inheritance - Everything You Need To Know - Dr. Nabil Ebraheim
Dr. Ebraheim’s educational animated video explains the X-Linked dominant inheritance and provides you with examples and simple pedigree to help comprehend all you need to know about this inheritance type. X-linked dominance will not skip a generation. Examples in orthopedics: 1-Hypophosphatemic rickets( vitamin D resistant rickets) 2-Leri-weill Dyschondrosteosis (LWD): is a dominantly inherited skeletal dysplasia, characterized by short stature, mesomelia, and madelung wrist deformity. Hypophosphatemic rickets( vitamin D resistant rickets) X-linked hypophosphatemic rickets with inability of the renal tubules to absorb phosphates (phosphates levels are down linked to PHEX gene- Phosphate Regulating Endopeptidase Homolog, X-linked). It is the most common cause of rickets in the United States of America. Look at these three factors: 1-Child is sort in stature 2-Bowing of the lower limbs 3-Low serum phosphate levels Since body is trying to compensate, so: 1-Alkaline phosphatase (ALP) levels will be high. 2-Calcium levels will be normal. 3-The parathyroid hormone will be normal. Treatment is usually high doses of phosphate replacement and high doses of vitamin D to facilitate the phosphate absorption. Leri-weill Dyschondrosteosis (LWD): A rare genetic disorder caused by mutation of the SHOX gene. Characterized by shortened stature caused by homeobox-containing gene and bilateral Madelung deformity of the forearm. If the mother is affected and the father is not affected, the condition will affect 50 % of the children and it will be equal in children males and females. If the father has the disease, none of the boys will get the disease but all the girls will get the disease. It will affect 50% of the children, but all the girls will be affected. The affected individual has an affected parent due to the dominant gene. All affected males must have an affected mother. All affected fathers will have affected daughters and no affected sons. Look at the males! Look at the sons and look at the fathers!

Water Soluble Vitamin Deficiency, Scurvy Pellagra Wernicke-Korsakoff Syndrome Beriberi
http://www.stomponstep1.com/water-soluble-vitamin-deficiency-scurvy-pellagra-wernicke-korsakoff/ Thiamine (Vitamin B1) deficiencies are primarily seen in alcoholic patients. This scenario is so common on Step 1 that anytime you see alcoholism in a vitamin question, your first thought should be thiamine deficiency. Thiamine is found in a lot of different foods, so you usually only see deficiencies in people who are malnourished or getting a majority of their calories from alcohol. Deficiencies of Thiamine primarily affect 3 different areas; the CNS (Wernicke-Korsakoff Syndrome), PNS (Dry Beri-Beri), and the cardiac system (Wet Beri-Beri). Damage done to the cardiac system and the PNS can be reversed with treatment, but damage done to the CNS is permanent. Thiamine is an important cofactor in multiple processes that generate ATP from glucose sugar. Therefore, deficiencies are worsened by sugar intake (in the absence of thiamine administration) because the little bit of Thiamine left in the system is used up to metabolize the sugar. Wernicke-Korsakoff Syndrome is the collection of CNS damage that results from Thiamine deficiency. It includes amnesia (memory loss), confusion, ataxia (unsteady gait), and visual disturbances due to uncoordinated eye movement. The confusion and memory loss can lead to confabulation in which the patient has bizarre explanations for things like how they got injured. Wernicke-Korsakof syndrome characteristically affects the Mammillary Bodies and the surrounding structures (3rd/4th ventricle & aqueduct). Infarcts or hemorrhages in these areas can be seen on radiologic imaging. Dry BeriBeri is damage to the peripheral nervous system (PNS) that results from Thiamine deficiency. It causes muscle wasting, weakness, and diminished peripheral sensation. Wet BeriBeri is the cardiac effects of Thiamine deficiency. It leads to arrhythmias and/or heart failure by affecting the electrical system of the heart. Edema, dyspnea, increased cardiac output, and cardiac dilation can result. Niacin (Vitamin B3) is part of NAD+ and NADP+ which carry electrons in redox reactions. Vitamin B3 is made from tryptophan using a vitamin B6 cofactor. Therefore, Niacin deficiency can be the result of Vitamin B6 deficiency or tryptophan deficiency (Hartnup Disease or Carcinoid Syndrome). Niacin deficiency is called Pellagra. Pellagra is characterized by the "4 Ds" Diarrhea, Dementia, Dermatitis, and Death. Niacin is one way to treat high cholesterol. Niacin toxicity can result if a patient receives too high of a dose. This causes the side effect of Facial Flushing (red face with the sensation of warmth). Pyridoxine (Vitamin B6) is an essential coenzyme in many metabolic reactions. Deficiencies can cause peripheral neuropathy (numbness & tingling), seizures, anemia & irritability. Deficiencies of Vitamin B6 can also lead to deficiencies of Vitamin B3, because B6 is a cofactor in the pathway that converts Tryptophan to Vitamin B3. The most common cause of Vitamin B3 deficiency is Isoniazid (TB drug) Treatment. Therefore, some patients receiving Isoniazid are given B6 vitamins prophylactically. Vitamin C (Ascorbic Acid) is involved in the hydroxylation of certain amino acids in collagen that are important for crosslinking individual pro-collagen chains into a triple helix. Without this hydroxylation the collagen is very weak. Therefore, deficiencies of Vitamin C cause poor wound healing, gum abnormalities (pain, bleeding & loose/missing teeth) & bruising (purpura, ecchymosis, perifollicular hemorrhages). Scurvy results from not eating enough fruit and other fresh foods.

Scientists may be close to finding genetic cause of type 2 diabetes
University College London Researchers have reported that they are closer to unlocking the genetic causes of type 2 diabetes after identifying 111 new chromosome locations, in the human genome. Previous studies had identified only 76 chromosome locations, and very few of them were found in the African-American population, where type 2 diabetes is twice as prevalent as in U.S. descendants of European ancestry. The study found that the additional 111 locations and previously known 76 locations regulate the expression of at least 266 genes that are next to the identified disease chromosome locations. http://www.upi.com/Health_News/2017/05/08/Scientists-may-be-close-to-finding-genetic-cause-of-type-2-diabetes/8281494261004/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Quantitative Genetics - How to find number of genes controlling the trait
QUANTITATIVE TRAITS Most phenotypic traits in plants and animals are affected by many genes (size, weight, shape, lifespan, physiological traits, fecundity). Often, it is not feasible to determine the number of genes affecting a particular trait, and the individual effects of genes on the phenotype. Many of these traits can be measured on a quantitative, rather than a qualitative, scale. This is where the terms quantitative trait and quantitative genetics come from. Quantitative traits: 1. Have continuous distributions, not discrete classes 2. Are usually affected by many genes (polygenic) 3. Are also affected by environmental factors EXAMPLE: COLOR OF WHEAT KERNELS This trait is determined by two genes that contribute "doses" of red pigment, and display partial dominance (heterozygotes intermediate). Each allele with the subscript "1" contributes 1 dose of red pigment. This trait demonstrates additive effects among different alleles at a single locus, and among alleles at different genetic loci. Genes with subscript "2 " don't contribute any red pigment. Polygenic inheritance refers to inheritance of a phenotypic characteristic (trait) that is attributable to two or more genes and can be measured quantitatively. Multifactorial inheritance refers to polygenic inheritance that also includes interactions with the environment. Unlike monogenic traits, polygenic traits do not follow patterns of Mendelian inheritance (separated traits). Instead, their phenotypes typically vary along a continuous gradient depicted by a bell curve. An example of a polygenic trait is human skin color variation. Several genes factor into determining a person's natural skin color, so modifying only one of those genes can change skin color slightly or in some cases, such as for SLC24A5, moderately. Many disorders with genetic components are polygenic, including autism, cancer, diabetes and numerous others. Most phenotypic characteristics are the result of the interaction of multiple genes.

How Geneticists Link Genes to Diseases
The former director of the National Human Genome Research Institute describes how researchers compare DNA sequences to pinpoint which genes cause which diseases. Question: During your work on the human genome, you linked many genes to specific diseases. How are these links established?Francis Collins:  It's too bad you can't actually see DNA easily under a microscope and scan across a double helix and read out the sequence of bases that amounts to the information content because it would be easier, I think, to explain then how a geneticist goes about tracking down the molecular basis of a disease at the molecular level.  Our methods are indirect—they're very powerful, they're really highly accurate, but they're not as visual as you might like.  We do have methods though, now, that allow you to read out with high accuracy, all three billion of the letters of the DNA instruction book, those letters are actually these chemical bases.  The chemical language of a DNA is a simple one, there's only four letters in the alphabet.  Those bases that we abbreviate A, C, G and T.  and we have methods of being able to compare then the DNA sequence of people who have a disease versus people who don't and look for the critical differences in order to nail down something that might be the cause.   Well since, however, we all differ in our DNA sequence by about a half of one percent, you wouldn't get very far if you basically sequenced my DNA and the DNA of somebody with Parkinson's Disease trying to figure out what the differences were because it would be way too many of them. But if you're willing to do that for a large number of people, you kind of average out all the noise and the difference that matters begins to be more and more clear.  That's an overly simplified description of how a geneticists goes about zeroing in on the actual molecular cause of a complex or a simple disease.  This works most readily for diseases that are highly heritable; cystic fibrosis, Huntington's Disease—those are conditions where as single mutation very reproducibly results in the disease.   It's been a lot tougher for diseases where the inheritance is muddy.  If you take diabetes, for instance, which is what my lab primarily works on, or you take asthma or high blood pressure, that is not a set of conditions where one gene is involved in risk, there are dozens of genes involved in that and no single one of them contributes very much, but you put it all together and the consequence to that individual may tip them over the threshold into having the illness.  We're in the throes right now trying to sort that part out for the common diseases that we know have hereditary influences because they run in families but they're much more complicated than say, cystic fibrosis. Question: Was there anything that totally surprised you in your research on the genome?Francis Collins: There were a lot of surprises a lot of times where you just marveled as what you had uncovered and felt like you must have really somehow missed it when you were making guesses about what would be there.  I guess the one that startled most us the most profoundly was how few protein coding genes there actually are in the genome.  The old paradigm about DNA-makes-RNA-makes-protein, well then a stretch of DNA is going to make a protein, how many genes does it take to specify a human being?  Hooh, you would think there would be an exorbitant number.  And various estimates have been put forward before we knew the answer that we're in the neighborhood of 100,000 to 150,000. Ultimately, it turns out we only have about 20,000 protein coding genes.  A breathtakingly short list of instructions for an organism as complex as homo sapiens.   There are other genes that don't code for protein that are turning out to be pretty important, so in a certain way we're rescuing our sense of complexity by discovering there are other categories or genes that don't have to be of the protein coding sort, but it is still astounding to think that just 20,000 of these protein coding genes is enough to take a single cell, which we all once were and inspire this program of elaborate complex development into a human being, including a nervous which is beyond our ability at the present time to even quite contemplate because of its complexity.

Ptosis - Dominant genetic disorder problem and solution
Ptosis /ˈtoʊsɪs/ (from Greek Ptosis or πτῶσις, to "fall") is a drooping or falling of the upper or lower eyelid. The drooping may be worse after being awake longer, when the individual's muscles are tired. This condition is sometimes called "lazy eye", but that term normally refers to amblyopia. If severe enough and left untreated, the drooping eyelid can cause other conditions, such as amblyopia or astigmatism. This is why it is especially important for this disorder to be treated in children at a young age, before it can interfere with vision development. Ptosis occurs when the muscles that raise the eyelid (levator and superior tarsal muscles) are not strong enough to do so properly. It can affect one eye or both eyes and is more common in the elderly, as muscles in the eyelids may begin to deteriorate. One can, however, be born with ptosis. Congenital ptosis is hereditary in three main forms. Causes of congenital ptosis remain unknown. Ptosis may be caused by damage/trauma to the muscle which raises the eyelid, damage to the superior cervical sympathetic ganglion or damage to the nerve (3rd cranial nerve (oculomotor nerve)) which controls this muscle. Such damage could be a sign or symptom of an underlying disease such as diabetes mellitus, a brain tumor, a pancoast tumor (apex of lung) and diseases which may cause weakness in muscles or nerve damage, such as myasthenia gravis. Exposure to the toxins in some snake venoms, such as that of the black mamba, may also cause this effect. Ptosis can be caused by the aponeurosis of the levator muscle, nerve abnormalities, trauma, inflammation or lesions of the lid or orbit. Dysfunctions of the levators may occur as a result of a lack of nerve communication being sent to the receptors due to antibodies needlessly attacking and eliminating the neurotransmitter. Ptosis may be due to a myogenic, neurogenic, aponeurotic, mechanical or traumatic cause and it usually occurs isolated, but may be associated with various other conditions, like immunological, degenerative, or hereditary disorders, tumors, or infections Acquired ptosis is most commonly caused by aponeurotic ptosis. This can occur as a result of senescence, dehiscence or disinsertion of the levator aponeurosis. Moreover, chronic inflammation or intraocular surgery can lead to the same effect. Also, wearing contact lenses for long periods of time is thought to have a certain impact on the development of this condition. Congenital neurogenic ptosis is believed to be caused by the Horner syndrome. In this case, a mild ptosis may be associated with ipsilateral ptosis, iris and areola hypopigmentation and anhidrosis due to the paresis of the Mueller muscle. Acquired Horner syndrome may result after trauma, neoplastic insult, or even vascular disease. Ptosis due to trauma can ensue after an eyelid laceration with transection of the upper eyelid elevators or disruption of the neural input. Other causes of ptosis include eyelid neoplasms, neurofibromas or the cicatrization after inflammation or surgery. Mild ptosis may occur with aging. As a precautionary action, a person who notices a drooping eyelid, uneven dilation of one pupil, or even minor changes, such as delayed movement of one eye, should contact a neurologist. A drooping eyelid can be one of the first signals of a third nerve palsy due to a cerebral aneurysm, that otherwise is asymptomatic and referred to as an oculomotor nerve palsy. A person experiencing this condition would be wise to seek a neurologist who would order a CT scan to rule out the possibility of a cranial aneurysm being present or in development.
Genetics of Sickle Cell Disease
Sickle cell disease is an inherited genetic disorder and is a recessive trait. This video describes how the genetic mutation causing sickle cell disease is passed on from mother to father, and explains how and why it is a recessive trait that requires gene mutations passed from both mother and father to become a symptomatic disease. This is one part of a series of videos about sickle cells disease. Here is an outline of the series: 1. Introduction to Sickle Cell Disease: http://youtu.be/z65z6JqWIG0 2.

Phenylketonuria | Biochemistry & Genetics
Phenylketonuria (PKU) is an inborn error of metabolism that results in decreased metabolism of the amino acid phenylalanine.[2] Untreated PKU can lead to intellectual disability, seizures, behavioral problems, and mental disorder. It may also result in a musty smell and lighter skin. Babies born to mothers who have poorly treated PKU may have heart problems, a small head, and low birth weight.[1] Phenylketonuria is a genetic disorder inherited from a person's parents. It is due to mutations in the PAH gene which results in low levels of the enzyme phenylalanine hydroxylase. This results in the build up of dietary phenylalanine to potentially toxic levels. It is autosomal recessive meaning that both copies of the gene must be mutated for the condition to develop. There are two main types, classic PKU and variant PKU, depending on if any enzyme function remains. Those with one copy of a mutated gene typically do not have symptoms.[1] Many countries have newborn screening programs for the disease.

What is GENETIC ARCHITECTURE? What does GENETIC ARCHITECTURE mean? GENETIC ARCHITECTURE meaning - GENETIC ARCHITECTUR definition - GENETIC ARCHITECTUR explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Genetic architecture refers to the underlying genetic basis of a phenotypic trait and its variational properties. Phenotypic variation for quantitative traits is, at the most basic level, the result of the segregation of alleles at quantitative trait loci (QTL). Environmental factors and other external influences can also play a role in phenotypic variation. Genetic architecture is a broad term that can be described for any given individual based on information regarding gene and allele number, the distribution of allelic and mutational effects, and patterns of pleiotropy, dominance, and epistasis. There are several different experimental views of genetic architecture. Some researchers recognize that the interplay of various genetic mechanisms is incredibly complex, but believe that these mechanisms can be averaged and treated, more or less, like statistical noise. Other researchers claim that each and every gene interaction is significant and that it is necessary to measure and model these individual systemic influences on evolutionary genetics. Genetic architecture can be studied and applied at many different levels. At the most basic, individual level, genetic architecture describes the genetic basis for differences between individuals, species, and populations. This can include, among other details, how many genes are involved in a specific phenotype and how gene interactions, such as epistasis, influence that phenotype. Line-cross analyses and QTL analyses can be used to study these differences. This is perhaps the most common way that genetic architecture is studied, and though it is useful for supplying pieces of information, it does not generally provide a complete picture of the genetic architecture as a whole. Genetic architecture can also be used to discuss the evolution of populations. Classical quantitative genetics models, such as that developed by R.A. Fisher, are based on analyses of phenotype in terms of the contributions from different genes and their interactions. Genetic architecture is sometimes studied using a genotype-phenotype map, which graphically depicts the relationship between the genotype and the phenotype. Genetic architecture is incredibly important for understanding evolutionary theory because it describes phenotypic variation in its underlying genetic terms, and thus it gives us clues about the evolutionary potential of these variations. Therefore, genetic architecture can help us to answer biological questions about speciation, the evolution of sex and recombination, the survival of small populations, inbreeding, understanding diseases, animal and plant breeding, and more.

Sickle Cell Trait
Sickle cell trait (or sicklemia) describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both normal and abnormal hemoglobin (the two alleles are codominant with respect to the actual concentration of hemoglobin in the circulating cells)

Sarah Tishkoff (U. Pennsylvania) Part 2: African Genomics: African Population History
Dr. Tishkoff begins with an overview of the evolution of modern humans and their migration out of Africa. She explains how and why population geneticists study both nuclear and mitochondrial DNA and how DNA comparisons have allowed scientists to determine when distinct hominid groups diverged and when and where these populations migrated across the globe. In Part 2, Tishkoff moves to the study of genetic diversity in present day African and African America populations. Genetic variation is higher in Africans than in Europeans or Asians, a result of the evolutionary history of humans. Patterns of diversity at specific genetic loci provide insight into the migrations and mixing of specific linguistic groups within Africa, as well as information about the ancestry of African Americans. In the final part of her talk, Tishkoff describes two examples of natural selection in humans. She and her colleagues identified 3 novel genetic variants associated with the ability of some African pastoralists to digest lactose. Using high coverage genome sequencing, Tishkoff also identified a candidate chromosomal region associated with short stature in Pygmies. Interestingly, this same region showed enrichment for genes involved in pituitary function such as metabolism and immunity. These results suggest that adaptation to local environments may result in region specific genetic adaptation. Biography Sarah Tishkoff studied anthropology and genetics as an undergraduate at the University of California, Berkeley. She received her PhD in genetics from Yale University and was a post-doctoral fellow at Pennsylvania State University. From 2000-2007, she was a faculty member in the Department of Biology at the University of Maryland. Currently, Dr. Tishkoff is the David and Lyn Silfen University Professor at the University of Pennsylvania in the Departments of Genetics and Biology. Tishkoff's lab studies genetic variation at the genome level in populations throughout the world, with an emphasis on Africa. She is interested in understanding how evolutionary forces have shaped and maintained genetic variation. Were genetic mutations now associated with common diseases such as diabetes or hypertension originally adaptive to historical environments? Could they have provided resistance to local infectious diseases or other benefits? Tishkoff also uses genetic data to study human evolution and human migration; both ancient and more recent migrations such as the slave trade. Tishkoff's innovative research has been recognized with numerous awards including the NIH Director's Pioneer Award for scientists of exceptional creativity.
