Several genes whose mutations cause monogenic diabetes (CEL and HNF1B)61–63, predispose to type 2 diabetes (RBPJL)64, or cause cystic dysplasia (NPHP3)65 or exocrine insufficiency (UBR1)66 were detected in our dataset in these early stages of development. The gene discussed is HNF1B; the disease is monogenic diabetes.
