Genes affected

GHSR (HGNC:4267): (growth hormone secretagogue receptor) This gene encodes a member of the G-protein coupled receptor family. The encoded protein may play a role in energy homeostasis and regulation of body weight. Two identified transcript variants are expressed in several tissues and are evolutionary conserved in fish and swine. One transcript, 1a, excises an intron and encodes the functional protein; this protein is the receptor for the Ghrelin ligand and defines a neuroendocrine pathway for growth hormone release. The second transcript (1b) retains the intron and does not function as a receptor for Ghrelin; however, it may function to attenuate activity of isoform 1a. Mutations in this gene are associated with autosomal idiopathic short stature.[provided by RefSeq, Apr 2010]

This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 204 of the GHSR protein (p.Ala204Glu). This variant is present in population databases (rs121917883, gnomAD 0.005%). This missense change has been observed in individual(s) with GFSR-related conditions (PMID: 14715843, 16511605, 25557026). ClinVar contains an entry for this variant (Variation ID: 7632). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GHSR protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects GHSR function (PMID: 16511605, 17596538, 17717076, 21084395). 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.
