Hum Mol Genet. 2020 Aug 3;29(13):2148–2161. doi: doi:10.1093/hmg/ddaa100. https://www.ncbi.nlm.nih.gov/pubmed/32452519This study explores the hitherto unknown role of FGF9 in human testis development. The authors use two mouse models that phenocopy the skeletal defects of dominant FGF9 mutations that cause skelet...

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.
