Answer:
Type 1 diabetes is an autoimmune disorder in which the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. The exact cause of type 1 diabetes is not fully understood, but it is thought to be a combination of genetic and environmental factors.
Regarding the genetic code, there is no specific single gene that is responsible for type 1 diabetes, but several genetic variations are associated with increased susceptibility to the disease. For example, studies have identified specific variations in genes that are involved in the immune system and in beta cell function, such as the HLA region on chromosome 6, which encodes for the human leukocyte antigen, a protein that plays a critical role in the immune system.
Type 1 diabetes is not located on one specific chromosome. It is a multigenic disorder, which means that it is caused by a combination of genetic variations that affect multiple genes on different chromosomes.
It is not a specific gene mutation (insertion, deletion, substitution) but it is more likely a complex combination of genetic variations that affect multiple genes on different chromosomes.
It can be passed on to offspring and it can be inherited from parents. However, it is not a simple Mendelian inheritance. It is a multifactorial disorder, which means that it is caused by a combination of genetic and environmental factors.
Type 1 diabetes is not sex-linked (on the 23rd pair of chromosomes). It affects both males and females equally.
