Genes affected
LPAR2 (HGNC:3168): (lysophosphatidic acid receptor 2) This gene encodes a member of family I of the G protein-coupled receptors, as well as the EDG family of proteins. This protein functions as a lysophosphatidic acid (LPA) receptor and contributes to Ca2+ mobilization, a critical cellular response to LPA in cells, through association with Gi and Gq proteins. An alternative splice variant has been described but its full length sequence has not been determined. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.629G>A (p.R210H) alteration is located in exon 2 (coding exon 1) of the LPAR2 gene. This alteration results from a G to A substitution at nucleotide position 629, causing the arginine (R) at amino acid position 210 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
