RPL22

Chr 1

ribosomal protein L22

Also known as: EAP, HBP15, HBP15/L22, L22, eL22

The RPL22 protein is a component of the large 60S ribosomal subunit that synthesizes proteins in the cell. Mutations cause Diamond-Blackfan anemia, an inherited bone marrow failure syndrome with autosomal dominant inheritance. The gene shows moderate tolerance to loss-of-function variants, which is typical for ribosomal protein genes associated with Diamond-Blackfan anemia.

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.
