CNTROB

Chr 17

centrobin, centriole duplication and spindle assembly protein

Also known as: LIP8, PP1221

NCBI Gene: 116840ENSG00000170037UniProt: Q8N137OMIM: 611425

The protein is required for centriole duplication and proper cytokinesis, with inhibition of centriole duplication leading to cytokinetic defects. Mutations cause autosomal dominant disease through a dominant-negative mechanism. The gene shows tolerance to loss-of-function variants based on constraint metrics, suggesting the pathogenic mechanism involves disruption of normal protein function rather than simple haploinsufficiency.

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.

GOFprediction above median

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.
