Genes affected

PLD1 (HGNC:9067): (phospholipase D1) This gene encodes a phosphatidylcholine-specific phospholipase which catalyzes the hydrolysis of phosphatidylcholine in order to yield phosphatidic acid and choline. The enzyme may play a role in signal transduction and subcellular trafficking. Alternative splicing results in multiple transcript variants with both catalytic and regulatory properties.

The c.3008G>A (p.R1003Q) alteration is located in exon 27 (coding exon 26) of the PLD1 gene. This alteration results from a G to A substitution at nucleotide position 3008, causing the arginine (R) at amino acid position 1003 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
