Genes affected

S1PR4 (HGNC:3170): (sphingosine-1-phosphate receptor 4) This gene is a member of the endothelial differentiation, G-protein-coupled (EDG)) receptor gene family. EDG receptors bind lysophospholipids or lysosphingolipids as ligands, and are involved in cell signalling in many different cell types. This EDG receptor gene is intronless and is specifically expressed in the lymphoid tissue. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.346G>A (p.A116T) alteration is located in exon 1 (coding exon 1) of the S1PR4 gene. This alteration results from a G to A substitution at nucleotide position 346, causing the alanine (A) at amino acid position 116 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
