Background: An activation cascade of specific genes sets up the initiation of sex determination leading in males to testes formation and synthesis of testicular hormones. Disruption of this gene cascade may cause a spectrum of disorders/differences of sex development (DSD) phenotypes. Here we describe for the first time two sisters suffering from 46,XY DSD, who by whole exome sequencing were shown to carry a mutation in the X-linked StAR-related lipid transfer...

Drosophila melanogaster as a study model has already significantly contributed to the understanding of the mechanisms of many human diseases. So far D. melanogaster has rarely been exploited as a model for human sex development. Nanda et.al already demonstrated in 2009 that the Drosophila orthologue of SOX9, Sox100B is essential for testis development in Drosophila. Similarly, we could demonstrate that the fly homolog of STARD8, cv-c</...
