Genes affected

PLD4 (HGNC:23792): (phospholipase D family member 4) Predicted to enable single-stranded DNA 5'-3' exodeoxyribonuclease activity. Predicted to be involved in hematopoietic progenitor cell differentiation; phagocytosis; and regulation of cytokine production involved in inflammatory response. Predicted to be located in early endosome and endoplasmic reticulum membrane. Predicted to be active in several cellular components, including endoplasmic reticulum; phagocytic vesicle; and trans-Golgi network membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.687T>G (p.S229R) alteration is located in exon 6 (coding exon 5) of the PLD4 gene. This alteration results from a T to G substitution at nucleotide position 687, causing the serine (S) at amino acid position 229 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
