Labcorp Genetics (formerly Invitae), Labcorp	RCV000726757	SCV001206884	pathogenic	not provided	2025-01-23	criteria provided, single submitter	clinical testing	This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 494 of the PRPF3 protein (p.Thr494Met). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with retinitis pigmentosa (PMID: 11773002, 15085354, 20309403, 28559085). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 3352). 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 expected to disrupt PRPF3 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects PRPF3 function (PMID: 17932117, 20811066). For these reasons, this variant has been classified as Pathogenic.
