PRPF6
Chr 20ADpre-mRNA processing factor 6
PRPF6 encodes a protein that functions as a component of the U4/U6-U5 tri-snRNP complex in the spliceosome, essential for pre-mRNA splicing, and also enhances steroid hormone receptor transactivation. Mutations cause autosomal dominant retinitis pigmentosa 60, a form of inherited retinal degeneration. The gene is highly constrained against loss-of-function variants (LOEUF 0.44), reflecting its essential role in RNA processing.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Highly missense-constrained (top ~0.1%)
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
