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

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000289 (44/152136) while in subpopulation AFR AF = 0.00104 (43/41482). AF 95% confidence interval is 0.00079. There are 0 homozygotes in GnomAd4. There are 26 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAd4 at 44 AD gene.
