CTR9

Chr 11

CTR9 component of Paf1/RNA polymerase II complex

Also known as: SH2BP1, TSBP, p150, p150TSP

The protein encoded by this gene is a component of the PAF1 complex, which associates with RNA polymerase II and functions in transcriptional regulation and elongation. This complex also plays a role in the modification of histones. [provided by RefSeq, Oct 2016]

CTR9-related neurodevelopmental disorder · ADModerate

Moderate evidence — consider for supplementary testing

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.

The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).

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.
