Genes affected

PLPPR5 (HGNC:31703): (phospholipid phosphatase related 5) The protein encoded by this gene is a type 2 member of the phosphatidic acid phosphatase (PAP) family. All type 2 members of this protein family contain 6 transmembrane regions, and a consensus N-glycosylation site. 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. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

The c.784A>G (p.I262V) alteration is located in exon 4 (coding exon 4) of the PLPPR5 gene. This alteration results from a A to G substitution at nucleotide position 784, causing the isoleucine (I) at amino acid position 262 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
