Genes affected

SOX3 (HGNC:11199): (SRY-box transcription factor 3) 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. Mutations in this gene have been associated with X-linked cognitive disability with growth hormone deficiency. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP3: Nonframeshift variant in repetitive region in NM_005634.3
• BS2: High Hemizygotes in GnomAd4 at 8 XL gene
