Background: Onset of diabetes in the neonatal period with additional malformations e.g. congenital heart defects should always be suspicious for an underlying genetic disorder. For example, GATA6-mutations were identified in children with congenital heart defects and neonatal diabetes. The latter may be due to pancreas agenesis. Herein we present a novel GATA6-mutation in a boy with transient neonatal diabetes, diaphragmatic hernia, congenital heart defect and early onset scol...

Introduction: Mammalian sex development is directly dependent on gonadal determination. Whole exome sequencing in patients with differences of sex development (DSD) allows the discovery of new factors involved in human sex development. One of these factors is NWD1 (NACHT and WD repeat domain containing 1) a cytosolic protein that seems to play a role in modulating androgen receptor signaling. We identified variants in the NWD1 gene in six und...

Abstract: Steroidogenic factor 1 (SF1)/"nuclear receptor subfamily 5 group A member 1" (NR5A1) is involved in adrenal and gonadal development, steroidogenesis and reproduction. The first patient, published in 1999 presented with a 46,XY difference of sex development (DSD) and adrenal insufficiency. The following year the first female patient with only adrenal insufficiency was described. Since then, heterozygous changes in SF-1/NR5A1 causing 46,XY DSD ...
