Genes affected

SOX5 (HGNC:11201): (SRY-box transcription factor 5) This gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins. The encoded protein may play a role in chondrogenesis. A pseudogene of this gene is located on chromosome 8. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 18 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 12-23740986-G-A is Pathogenic according to our data. Variant chr12-23740986-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 545592.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
