Transkriptionsfaktor HNF4alpha
Das Gen kodiert einen Transkriptionsfaktor der unter anderem die Expression des Transkriptionsfaktors HNF1-alpha reguliert. Mutationen lösen einen autosomal dominanten Diabetes MODY1 oder eine hyperinsulinämische Hypoglycämie aus.
Phänotyp
Neben einem MODY1 kann die Mutation R76W auch einen atypisches dominantes Fanconi-Syndrom auslösen[Error: Macro 'ref' doesn't exist]
