PubMed [citation] PMID: 30552336Initial steps in the sex determination of the (human) testis depend on SRY regulating SOX9, but the exact mechanism that controls SOX9 expression remains unknown. These authors discovered four overlapping copy number variations (CNVs) upstr...

Brief Summary: This translational study reveals a novel mechanism underlying syndromic gonadal dysgenesis (GD). It introduces a condition termed INDYGON syndrome (Intellectual disability, Neurodevelopmental defects and Developmental delay with 46,XY GONadal dysgenesis).46,XY gonadal dysgenesis (GD) is a rare disorder of sex development (DSD) affecting 1-9 per 100,000 live births.
