Laron-type isolated somatotropin defect Pathogenic:1Uncertain: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:2

This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 240 of the GHR protein (p.Tyr240His). This variant is present in population databases (rs143814221, gnomAD 0.05%). This missense change has been observed in individual(s) with growth hormone insensitivity (PMID: 10984309). This variant is also known as p.Tyr222His. ClinVar contains an entry for this variant (Variation ID: 198398). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on GHR protein function. 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. -
