CRYBG3

Chr 3

crystallin beta-gamma domain containing 3

Also known as: DKFZp667G2110, vlAKAP

CRYBG3 encodes an anchoring protein that mediates subcellular compartmentation of protein kinase A and is predicted to function in lens development and visual perception. The gene shows low constraint to loss-of-function variation. Currently, no well-established human diseases have been definitively linked to CRYBG3 mutations.

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.
