Genes affected

SOX9 (HGNC:11204): (SRY-box transcription factor 9) The protein encoded by this gene recognizes the sequence CCTTGAG along with other members of the HMG-box class DNA-binding proteins. It acts during chondrocyte differentiation and, with steroidogenic factor 1, regulates transcription of the anti-Muellerian hormone (AMH) gene. Deficiencies lead to the skeletal malformation syndrome campomelic dysplasia, frequently with sex reversal. [provided by RefSeq, Jul 2008]

SOX9-AS1 (HGNC:49321): (SOX9 antisense RNA 1)

ENSG00000288605 (HGNC:):
