Summary: | Both genetic and environmental factors contribute to the etiology of
non-insulin-dependent diabetes. The genetic component is heterogeneous and in
some patients is probably complex, involving multiple genes. Specific genetic
defects have been identified for rare monogenic forms of NIDDM: maturity-onset
diabetes of the young, or MODY (which is due to glucokinase mutations in about
40% of families), syndromes of extreme insulin resistance (which often
involve the insulin receptor), and diabetes-deafness syndromes (with defects in
mitochondrial genes). In contrast, the genes involved in common forms of NIDDM
are still uncertain. Mutations have been extensively searched in genes
regulating insulin signaling and secretion. Some evidence of involvement has
been produced for insulin-receptor substrate-1, glycogen synthase, the glucagon
receptor, a ras-related protein (Rad), histocompatibility antigens, PC-1, and
fatty acid binding protein, but the contribution of these genes to NIDDM is
probably small. Other candidate genes (e.g. insulin, insulin receptor, glucose
transporters) have been excluded as major diabetogenes. New insights are
expected in the near future from the systematic scanning of the genome for
linkage with NIDDM. |
