CD72
Chr 9CD72 molecule
CD72 encodes a B cell co-receptor that regulates B cell receptor signaling through recruitment of phosphatases and maintains regulatory T and B cell homeostasis. Mutations cause common variable immunodeficiency with autosomal recessive inheritance. The gene shows moderate constraint against loss-of-function variants, suggesting some tolerance to complete loss of function.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Mild missense constraint
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.
