Cataract 5, multiple types (CTRCT5)2 Publications
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. CTRCT5 includes infantile, lamellar, zonular, nuclear, anterior polar, stellate, and Marner-type cataracts, among others. Finger malformation is observed in some kindreds.
