[Autosomal dominant mild juvenile diabetes mellitus (MODY) (author's transl)].

A family is described in which eleven members, over four generations, suffer from the autosomal dominant inherited maturity onset type diabetes of young people (MODY). A comparison of these findings with those of six families previously described in the literature shows in particular that: 1. manifestation of the disease is predominantly at a fairly young age, 2. the complaint is not insulin-dependent nor is it progressive, 3. when medical supervision is adequate, there are hardly any secondary complications, 4. the inheritance pattern is autosomal dominant with high penetrance and probably a stronger expressivity in the female. This disease can be separated from the classical, insulin-dependent diabetes of the young, from the autosomal dominant lipatrophic diabetes and from the heterozygous form of the autosomal recessive complaint, which in the homozygous state shows diabetes mellitus and insipidus with optic atrophy.
