Genes affected

LPCAT1 (HGNC:25718): (lysophosphatidylcholine acyltransferase 1) This gene encodes a member of the 1-acyl-sn-glycerol-3-phosphate acyltransferase family of proteins. The encoded enzyme plays a role in phospholipid metabolism, specifically in the conversion of lysophosphatidylcholine to phosphatidylcholine in the presence of acyl-CoA. This process is important in the synthesis of lung surfactant and platelet-activating factor (PAF). Elevated expression of this gene may contribute to the progression of oral squamous cell, prostate, breast, and other human cancers. [provided by RefSeq, Sep 2016]

The c.1444A>G (p.M482V) alteration is located in exon 14 (coding exon 14) of the LPCAT1 gene. This alteration results from a A to G substitution at nucleotide position 1444, causing the methionine (M) at amino acid position 482 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
