CENPP
Chr 9centromere protein P
Also known as: CENP-P
The protein is a component of the CENPA-CAD complex that targets CENPA to centromeres and is required for proper kinetochore function, mitotic progression, and chromosome segregation. Mutations cause microcephaly with intellectual disability and seizures through a dominant-negative mechanism. The condition follows an autosomal dominant inheritance pattern.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
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.
