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)

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-72121513-C-CG is Pathogenic according to our data. Variant chr17-72121513-C-CG is described in ClinVar as [Pathogenic]. Clinvar id is 1323635.Status of the report is criteria_provided_single_submitter, 1 stars.
