Variant 1-84865873-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 1P and 4B. PP3BS2

The NM_012152.3(LPAR3):c.248A>G(p.Tyr83Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000929 in 1,613,846 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y83N) has been classified as Uncertain significance.

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.

Ambry Genetics

May 17, 2023

The c.248A>G (p.Y83C) alteration is located in exon 2 (coding exon 1) of the LPAR3 gene. This alteration results from a A to G substitution at nucleotide position 248, causing the tyrosine (Y) at amino acid position 83 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
