Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_000163.5(GHR):c.724G>A(p.Glu242Lys) variant causes a missense change. The variant allele was found at a frequency of 0.0000657 in 1,612,960 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E242D) has been classified as Likely benign.

Laron-type isolated somatotropin defect Uncertain:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
not provided Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 242 of the GHR protein (p.Glu242Lys). This variant is present in population databases (rs121909364, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with GHR-related conditions. ClinVar contains an entry for this variant (Variation ID: 907708). 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 GHR protein function with a negative predictive value of 80%. 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. -
