Pathology & Biotechi

Involvement in diseasei

Cataract 20, multiple types (CTRCT20)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn 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. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function. CTRCT20 includes progressive polymorphic anterior, posterior, or peripheral cortical.
