Pedigree Analysis of Maturity-Onset Diabetes of the Young: ABCC8 Mutations?
Background:
Maturity-Onset Diabetes of the Young (MODY) is an autosomal dominant disease, caused by muta-tions in the ABCC8 gene, chromosome 11.
Methods:
A case suspected of MODY due to an ABCC8 mutation was examined using whole-genome exon high-throughput sequencing. Selected variant sites were validated via Sanger sequencing.
Results:
A heterozygous mutation c.2060C>T (p.T687M) in exon 15 of the ABCC8 gene (Chr11-174494701) was identified in both the proband and the father. This mutation was initially linked to MODY based on clinical fea¬tures.
Conclusions:
For patients with high suspicion of MODY, genetic test should conducted to improve their quality of life.

Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
