ART3

Chr 4

ADP-ribosyltransferase 3 (inactive)

Also known as: ARTC3

The protein is an arginine-specific ADP-ribosyltransferase that catalyzes the addition or removal of ADP-ribose to arginine residues on target proteins to regulate their function. The gene is extremely intolerant to loss-of-function variants (pLI near 1.0), suggesting that complete loss of protein function would be incompatible with normal development. However, no specific human diseases have been definitively associated with ART3 mutations in the current literature.

The highest-scoring mechanism for this gene is gain-of-function.

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.
