Introduction: PCSK1/3 gene mutations are known as a cause for congenital diarrhea and various endocrinopathies. Hypogonadotrophic hypogonadism and aberrant pubertal development due to pro-convertase dysfunction was not characterized yet. This study aimed to characterize the pubertal development in a family carrying the novel N309K mutation in the PCSK1 gene.Methods and Results: We Identified 2 siblings who presented with severe congenital diarrhea follow...

Background: Wolfram syndrome type 2 (WFS2) characterized by childhood GI ulcers/ bleeding, diabetes, and neurodegeneration with optic atrophy and hearing loss was recently elucidated as caused by CISD2/NAF-1 gene mutation. NAF-1 suppression in cells results in intra-mitochondrial accumulation of iron, increased ROS generation and consequently increased cellular apoptosis. So far only two mutations in four families were reported.Objective: Elucidate the c...
