Maturity-Onset Diabetes Of The Young, Type 7

A number sign (#) is used with this entry because of evidence that maturity-onset diabetes of the young type 7 (MODY7) is caused by heterozygous mutation in the KLF11 gene (603301) on chromosome 2p25.

For a phenotypic description and a discussion of genetic heterogeneity of MODY, see 606391.

Molecular Genetics

Neve et al. (2005) sequenced the KLF11 gene in 190 probands of families with early-onset type II diabetes mellitus and identified a SNP (A349S; 603301.0001) in affected members of a 4-generation family and another SNP (T220M; 603301.0002) in affected members of 2 unrelated multigenerational families. In 1 of the latter families, the T220M variant was not found in a diabetic sib with disease onset at a later age. Neither variant was found in 313 patients with late-onset type II diabetes or in 313 normoglycemic individuals.
