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 Benign. Variant got -11 ACMG points.

• PP2: Missense variant where missense usually causes diseases, SOX5
• BP4: Computational evidence support a benign effect (MetaRNN=0.14227864).
• BP6: Variant 12-23534384-G-C is Benign according to our data. Variant chr12-23534384-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 3167798.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000547 (8/1461868) while in subpopulation EAS AF= 0.000151 (6/39696). AF 95% confidence interval is 0.0000651. There are 0 homozygotes in gnomad4_exome. There are 2 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAdExome at 8 AD gene.

Ambry Genetics

Dec 15, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
