Rare form of Permanent Neonatal Diabetes Mellitus (PNDM) due to novel mutation in EIF2AK3 gene (Wolcott—Rallison syndrome)

Abstract

Wolcott—Rallison syndrome (WRS) is a rare genetic disease inherited in autosomal recessive way. Сlinical manifestations develop in early infancy with symptoms of permanent neonatal diabetes mellitus (PNDM), skeletal dysplasia, short stature and hepatic dysfunction. The condition has poor prognosis and most patients die at a young age due to episodes of acute liver or renal failure. To date about 60 genetically proved cases of WRS have been reported worldwide. The disease is most common in countries where consanguineous marriages are frequent, such as the Saudi Arabia (60% cases of PNDM patients), India, Turkey, Pakistan and North Africa. In Russian Federation WRS patients have not been described earlier.
