CRYBG2

Chr 1

crystallin beta-gamma domain containing 2

Also known as: AIM1L

CRYBG2 encodes a protein predicted to bind carbohydrates, though its specific physiological function remains unclear. The gene shows minimal constraint against loss-of-function variants (pLI near 0, LOEUF 0.793), suggesting that complete loss of function may be tolerated. Currently, no established human genetic diseases have been definitively linked to CRYBG2 mutations.
