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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SOX5. . Gene score misZ 3.1513 (greater than the threshold 3.09). Trascript score misZ 3.799 (greater than threshold 3.09). GenCC has associacion of gene with Lamb-Shaffer syndrome, developmental and speech delay due to SOX5 deficiency.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.778
