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 GeneticsJan 23, 2024The c.664G>A (p.A222T) alteration is located in exon 6 (coding exon 6) of the LPCAT4 gene. This alteration results from a G to A substitution at nucleotide position 664, causing the alanine (A) at amino acid position 222 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
