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.2917G>T (p.D973Y) alteration is located in exon 26 (coding exon 25) of the PLD1 gene. This alteration results from a G to T substitution at nucleotide position 2917, causing the aspartic acid (D) at amino acid position 973 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
