Genes affected

PLPP3 (HGNC:9229): (phospholipid phosphatase 3) The protein encoded by this gene is a member of the phosphatidic acid phosphatase (PAP) family. PAPs convert phosphatidic acid to diacylglycerol, and function in de novo synthesis of glycerolipids as well as in receptor-activated signal transduction mediated by phospholipase D. This protein is a membrane glycoprotein localized at the cell plasma membrane. It has been shown to actively hydrolyze extracellular lysophosphatidic acid and short-chain phosphatidic acid. The expression of this gene is found to be enhanced by epidermal growth factor in Hela cells. [provided by RefSeq, Mar 2010]

The c.845C>T (p.T282M) alteration is located in exon 6 (coding exon 6) of the PLPP3 gene. This alteration results from a C to T substitution at nucleotide position 845, causing the threonine (T) at amino acid position 282 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
