MODY1 diabetes

MODY1 is an autosomal dominant early-onset type 2 diabetes caused by mutations of the HNF4A gene.

Epidemiology

There are only some few cases reported throughout the word.

Test Strategy

The diagnostic procedures generally are the same for all types of MODY diabetes.

Pathogenesis

This gene is in the same signaling cascade as TCF1, the gene where defects are responsible for MODY3. Therefore the pathogenesis and clinical expression are similar.
