Background: Though the genes and signalling pathways involved in sexual development have only been partially elucidated, it is known that their disruption can result in disorders of sexual development (DSD). XX ovarian dysgenesis (XX-OD) is a rare, genetically heterogeneous disorder characterized by underdeveloped and dysfunctional ovaries. We previously identified a novel missense mutation in Nucleoporin107 (Nup107, c.1339G>A, p.D447N), an essential compo...

Background: Nicotinamide nucleotide transhydrogenase (NNT) gene mutations have been recently shown to cause familial glucocorticoid deficiency (FGD), by decreasing reactive oxygen species (ROS) detoxification in adrenocortical cells. Affected infants present within the first few months with isolated glucocorticoid deficiency.Objective and Hypotheses: To study the genetic etiology of four cases presenting uniquely with neonatal addisonian crisis (both min...

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...
