Genes affected

LPAR1 (HGNC:3166): (lysophosphatidic acid receptor 1) The integral membrane protein encoded by this gene is a lysophosphatidic acid (LPA) receptor from a group known as EDG receptors. These receptors are members of the G protein-coupled receptor superfamily. Utilized by LPA for cell signaling, EDG receptors mediate diverse biologic functions, including proliferation, platelet aggregation, smooth muscle contraction, inhibition of neuroblastoma cell differentiation, chemotaxis, and tumor cell invasion. Many transcript variants encoding a few different isoforms have been identified for this gene. [provided by RefSeq, Oct 2020]

The c.731C>T (p.S244F) alteration is located in exon 4 (coding exon 2) of the LPAR1 gene. This alteration results from a C to T substitution at nucleotide position 731, causing the serine (S) at amino acid position 244 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
