Genes affected
LPCAT4 (HGNC:30059): (lysophosphatidylcholine acyltransferase 4) Members of the 1-acylglycerol-3-phosphate O-acyltransferase (EC 2.3.1.51) family, such as AGPAT7, catalyze the conversion of lysophosphatidic acid (LPA) to phosphatidic acid (PA), a precursor in the biosynthesis of all glycerolipids. Both LPA and PA are involved in signal transduction (Ye et al., 2005 [PubMed 16243729]).[supplied by OMIM, May 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.1409A>G (p.Q470R) alteration is located in exon 14 (coding exon 14) of the LPCAT4 gene. This alteration results from a A to G substitution at nucleotide position 1409, causing the glutamine (Q) at amino acid position 470 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
