CD47
Chr 3CD47 molecule
Also known as: IAP, MER6, OA3
The protein CD47 is a membrane adhesion protein that serves as a receptor for thrombospondin and modulates integrin signaling, playing roles in cell-to-cell interactions, cardiovascular homeostasis, inflammation, and immunoregulation. Mutations cause autosomal recessive defects affecting multiple systems including hematologic, cardiovascular, and neurologic manifestations. This gene is highly constrained against loss-of-function variants, indicating that complete loss of CD47 function is likely to cause significant clinical effects.
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 (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
