Genes affected

S1PR1 (HGNC:3165): (sphingosine-1-phosphate receptor 1) The protein encoded by this gene is structurally similar to G protein-coupled receptors and is highly expressed in endothelial cells. It binds the ligand sphingosine-1-phosphate with high affinity and high specificity, and suggested to be involved in the processes that regulate the differentiation of endothelial cells. Activation of this receptor induces cell-cell adhesion. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.39).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.304 is higher than 0.05.
