Genes affected
PRPF4 (HGNC:17349): (pre-mRNA splicing tri-snRNP complex factor PRPF4) The protein encoded by this gene is part of a heteromeric complex that binds U4, U5, and U6 small nuclear RNAs and is involved in pre-mRNA splicing. The encoded protein also is a mitotic checkpoint protein and a regulator of chemoresistance in human ovarian cancer. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2016]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 27, 2021In 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with PRPF4-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with serine at codon 12 of the PRPF4 protein (p.Thr12Ser). The threonine residue is weakly conserved and there is a small physicochemical difference between threonine and serine. -
