Genes affected

LPAR3 (HGNC:14298): (lysophosphatidic acid receptor 3) This gene encodes a member of the G protein-coupled receptor family, as well as the EDG family of proteins. This protein functions as a cellular receptor for lysophosphatidic acid and mediates lysophosphatidic acid-evoked calcium mobilization. This receptor couples predominantly to G(q/11) alpha proteins.

The c.406G>T (p.V136F) alteration is located in exon 2 (coding exon 1) of the LPAR3 gene. This alteration results from a G to T substitution at nucleotide position 406, causing the valine (V) at amino acid position 136 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
