Labcorp Genetics (formerly Invitae), Labcorp RCV001383203 SCV001582282 pathogenic not provided 2024-02-18 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 73 of the PROP1 protein (p.Arg73His). This variant is present in population databases (rs121917842, gnomAD 0.003%). This missense change has been observed in individual(s) with combined pituitary hormone deficiency (PMID: 11549703, 12859410, 23624138, 28734020). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is also known as Arg71His. ClinVar contains an entry for this variant (Variation ID: 8103). 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) has been performed at Invitae 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 PROP1 protein function. This variant disrupts the p.Arg73 amino acid residue in PROP1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9824293, 15531542, 25557026). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
