|Abstract||We report the case of a female patient suffering from a 46,XY disorder of sexual development (DSD) with complete gonadal dysgenesis and Wiedemann-Steiner Syndrome (WDSTS). The coexistence of these 2 conditions has not yet been reported. Using whole exome sequencing and comparative genome hybridization array, we identified a de novo MLL/KMT2A gene nonsense mutation which explains the WDSTS phenotype. In addition, we discovered novel genetic variants, which could explain the testicular dysgenesis observed in the patient, a maternally inherited 167-kb duplication of DAAM2 and MOCS1 genes and a de novo LRRC33/NRROS gene mutation. These genes, some of which are expressed during mouse gonadal development, could be considered as potentially new candidate genes for DSD.|
