Genes affected

S1PR3 (HGNC:3167): (sphingosine-1-phosphate receptor 3) This gene encodes a member of the EDG family of receptors, which are G protein-coupled receptors. This protein has been identified as a functional receptor for sphingosine 1-phosphate and likely contributes to the regulation of angiogenesis and vascular endothelial cell function.

Collection Method: clinical testing

The c.896C>T (p.T299M) alteration is located in exon 2 (coding exon 1) of the S1PR3 gene. This alteration results from a C to T substitution at nucleotide position 896, causing the threonine (T) at amino acid position 299 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
