Maturity-onset diabetes of the young (MODY) is a heterogeneous disorder
that appears to be characterized by a primary defect in insulin secretion.
Mutations in an unknown locus (MODY1) on chromosome 20 and the glucokinase
gene (MODY2) on chromosome 7 can cause this form of non-insulin-dependent
diabetes. Recent genetic studies have identified a third locus on
chromosome 12 (MODY3) that is linked to MODY in a group of French families.
We have identified three families from Denmark, Germany, and the U.S.
(Michigan) showing evidence of linkage with MODY3 and a family from Japan
showing suggestive evidence. Analysis of key recombinants in these families
localized MODY3 to a 5-cM interval between the markers D12S86 and
D12S807/D12S820.
