CRYBA1

CRYBA1 (Crystallin Beta A1) is a Protein Coding gene. Diseases associated with CRYBA1 include Cataract 10, Multiple Types and Cataract 25. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and structural constituent of eye lens. An important paralog of this gene is CRYBA4.

Cataract 10, multiple types (CTRCT10):
An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. CTRCT10 includes congenital zonular with sutural opacities, among others. This is a form of zonular cataract with an erect Y-shaped anterior and an inverted Y-shaped posterior sutural opacities. Zonular or lamellar cataracts are opacities, broad or narrow, usually consisting of powdery white dots affecting only certain layers or zones between the cortex and nucleus of an otherwise clear lens. The opacity may be so dense as to render the entire central region of the lens completely opaque, or so translucent that vision is hardly if at all impeded. Zonular cataracts generally do not involve the embryonic nucleus, though sometimes they involve the fetal nucleus. Usually sharply separated from a clear cortex outside them, they may have projections from their outer edges known as riders or spokes.

Specific cleavages in the N-terminal arm occur during lens maturation and give rise to several truncated forms. Cleavages do not seem to have adverse effects on solubility.
S-methylation and glutathionylation occur in normal young lenses and do not seem to be detrimental.
