RCV002795165 | SCV003021514 | uncertain significance | Familial hemophagocytic lymphohistiocytosis 2 | 2024-01-07 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 190 of the PRF1 protein (p.His190Tyr). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with PRF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1982898). 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 PRF1 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. |
