Genes affected

SOX1 (HGNC:11189): (SRY-box transcription factor 1) This intronless 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 activator after forming a protein complex with other proteins. In mice, a similar protein regulates the gamma-crystallin genes and is essential for lens development. [provided by RefSeq, Jul 2008]

SOX1-OT (HGNC:42733): (SOX1 overlapping transcript)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.23170212).

The c.668A>C (p.H223P) alteration is located in exon 1 (coding exon 1) of the SOX1 gene. This alteration results from a A to C substitution at nucleotide position 668, causing the histidine (H) at amino acid position 223 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
