Multiple sclerosis (MS) is a complex autoimmune disease influenced by multiple genetic factors rather than a single gene or chromosome. However, the HLA-DRB1 gene on chromosome 6 is notably associated with an increased risk of developing MS. Variants in this gene can affect immune response, contributing to the disease. Additionally, other genetic loci across various chromosomes have also been linked to MS susceptibility.
In ALS, also known as amyotrophic lateral sclerosis, the chromosome primarily affected is chromosome 9. A gene called C9orf72 located on this chromosome is linked to a significant percentage of familial ALS cases. Other genetic mutations on different chromosomes can also contribute to ALS development.
Obviously.
Chromosome 2
if you mean chromosome its the 15th......
Chromosome 21 is tripled in Down syndrome.
Chromosome number 8. (Gene: RECQL4 gene.)
nucleus → chromosome → gene
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
Barth syndrome occurs when a person is born with a mutated, or abnormal, TAZ1 (or G4.5) gene. This abnormal gene is located on the X chromosome, which is a sex-determining chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
Gene duplication is a type of mutation that can add genes to a chromosome. During gene duplication, a segment of DNA is copied and inserted into the chromosome, leading to an increase in the number of copies of a particular gene. This can result in gene families with multiple copies of a gene that may evolve new functions over time.
Chromosome numbers: 1, 14, 19, and 21 are affected by Alzheimer's disease.
The ear lobe trait is not located on a specific chromosome, as it is a common genetic trait that is not influenced by a single gene or located on a specific chromosome. The presence or absence of ear lobes is determined by multiple genetic factors.
