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.896G>A (p.R299Q) alteration is located in exon 5 (coding exon 5) of the PLPPR5 gene. This alteration results from a G to A substitution at nucleotide position 896, causing the arginine (R) at amino acid position 299 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
