UCLA Clinical Genomics Center, UCLA RCV000196330 SCV000255442 likely pathogenic Familial hemophagocytic lymphohistiocytosis 2 2014-04-22 criteria provided, single submitter clinical testing
Invitae RCV000196330 SCV001233846 pathogenic Familial hemophagocytic lymphohistiocytosis 2 2023-06-16 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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. ClinVar contains an entry for this variant (Variation ID: 216986). This missense change has been observed in individual(s) with familial hemophagocytic lymphohistiocytosis (PMID: 25326637, 26450956). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs751161742, gnomAD 0.01%). This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 446 of the PRF1 protein (p.Gln446Pro).
