CD2BP2
Chr 16CD2 cytoplasmic tail binding protein 2
Also known as: FWP010, LIN1, PPP1R59, Snu40, U5-52K
The protein functions as a component of the U5 small nuclear ribonucleoprotein complex involved in pre-mRNA splicing and also regulates T lymphocyte activation by binding to the CD2 surface antigen. Mutations cause autosomal recessive developmental and epileptic encephalopathy with onset in infancy, characterized by severe intellectual disability, refractory seizures, and progressive microcephaly. The gene shows tolerance to loss-of-function variants with a low constraint score.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
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.
