Genes affected

APLN (HGNC:16665): (apelin) This gene encodes a peptide that functions as an endogenous ligand for the G-protein coupled apelin receptor. The encoded preproprotein is proteolytically processed into biologically active C-terminal peptide fragments. These peptide fragments activate different tissue specific signaling pathways that regulate diverse biological functions including fluid homeostasis, cardiovascular function and insulin secretion. This protein also functions as a coreceptor for the human immunodeficiency virus 1. [provided by RefSeq, Feb 2016]

The c.176G>A (p.R59Q) alteration is located in exon 2 (coding exon 2) of the APLN gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
