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.

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 16, 2022	This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1018 of the PLD1 protein (p.Asp1018Asn). This variant is present in population databases (rs140678011, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with PLD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1412549). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jan 07, 2024	In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
