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.979G>A (p.A327T) alteration is located in exon 10 (coding exon 10) of the LPCAT1 gene. This alteration results from a G to A substitution at nucleotide position 979, causing the alanine (A) at amino acid position 327 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
