Genes affected

SOX17 (HGNC:18122): (SRY-box transcription factor 17) 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. [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
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.933

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C45"). This variant has been observed in individual(s) with pulmonary arterial hypertension (PMID: 30029678, Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with serine at codon 95 of the SOX17 protein (p.Asn95Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine. -
