What Is Mthfr Gene Mutation
Gene Mutation: This is a mutation in one of the genes that help to process iron absorption. The mutation, if present in 2 copies, can cause too much iron to be absorbed. The excess iron then deposits in other organs and can cause disease - cirrhosis, diabetes, impotence. Having only one mutation may not lead to disease. You should discuss this with your doctor to see if you are at risk of developing disease. ...Read more
From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
Mutations: A chromosome will contain many genes, so a chromosome mutation will effect many genes. A gene mutation will have an effect only on that gene. ...Read more
Gene for Factor VIII: Hemophilia a is a hereditary bleeding disorder where there is a deficiency in clotting factor viii (factor viii is needed for blood clotting). It is inherited on the x-chromosome (sex-linked). Men only have 1 "x", so if their "x" is mutated, they will have the disease. Women have 2 "x's", so they can have 1 mutated "x" and 1 normal "x", and be a carrier of the disease, with mild or no symptoms. ...Read more
8.6k genes on chrom: We have 20,000 genes on our 23 chromosomes. We have 2 copies of each chromosome except for the 23rd pair (X & Y in males and X & X in females). A gene mutation affects a single gene on one copy of one chromosome. A chromosomal abnormality affects many genes . It may be a 3rd copy or just a single copy of part/all of a chromosome or a 'translocation' can place part of a chromosome onto another. ...Read more
Progeria: Progeria is an extremely rare genetic disorder that may be seen at an early age and is unlikely to develop at age 48. Please go online to Wikipedia and read through the information. What is your height and weight? Are you getting shorter? Are you getting a change in weight? Once you have read the article you should probably see your doctor. ...Read more
Galactosemia genetic: Galactosemia is a disease that affects how body processes a sugar called galactose which is present e.g. In dairy. It is an autosomal recessive condition which means that each parent is a carrier of a nonfunctional copy of a gene. Because their other copy of that gene is functional they don't have symptoms. If both parents pass on the nonfunctional copy to a child, the child will have galactosemia. ...Read more
Neither: People normally have 2 beta globulin genes. A mutation in one or both genes leads to 3 levels of beta thalassemia. The genetics of the disorder is not all-or-none nor dominant-recessive. Instead, more or worse mutations causes worse disease. One mutation = beta thal trait (mild symptoms), 2 mutations = beta thal intermedia (transfusions sometimes) or beta thal major (lifelong transfusions needed). ...Read moreSee 1 more doctor answer
Flu virus genes: The hemaglutinin and neuraminidase genes are in influenza viruses. They code for proteins that are found on the surface of the flu virus. The viruses are named according to which type of hemaglutinin and neuraminidase proteins are on their surfaces (for example: h1n1 or h7n9). ...Read more

Size: Chromosomes are the large packages containing the genes, usually changes in the genes are called mutations and changes in the chromosomes are copy number variations or changes involving gain or loss of chromosome material ...Read more
In genetics, a mutation is a change in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element. Mutations result from unrepaired damage to dna or to RNA genomes (typically caused by radiation or chemical mutagens), from errors in the process of replication, or from the insertion or deletion of segments of dna ...Read more
