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 Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the SOX5 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 18 curated pathogenic missense variants (we use a threshold of 10). The gene has 12 curated benign missense variants. Gene score misZ: 3.1513 (above the threshold of 3.09). Trascript score misZ: 3.799 (above the threshold of 3.09). GenCC associations: The gene is linked to Lamb-Shaffer syndrome, developmental and speech delay due to SOX5 deficiency.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.89
• PP5: Variant 12-23536610-G-C is Pathogenic according to our data. Variant chr12-23536610-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 224817.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr12-23536610-G-C is described in Lovd as [Likely_pathogenic].
