Labcorp Genetics (formerly Invitae), Labcorp RCV003101467 SCV003519562 pathogenic Familial hemophagocytic lymphohistiocytosis 2 2024-12-16 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 168 of the PRF1 protein (p.Ser168Asn). This variant is present in population databases (rs779399414, gnomAD 0.05%). This missense change has been observed in individual(s) with clinical features of hemophagocytic lymphohistiocytosis (PMID: 20092789, 21674762, 25233452, 29357941, 29665027, 31388699). ClinVar contains an entry for this variant (Variation ID: 1694131). 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) indicates that this missense variant is not expected to disrupt PRF1 protein function with a negative predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.
