Summaries for Cone-Rod Dystrophy 21

UniProtKB/Swiss-Prot : 73 Cone-rod dystrophy 21: A form of cone-rod dystrophy, an inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa, due to cone photoreceptors degenerating at a higher rate than rod photoreceptors.

MalaCards based summary : Cone-Rod Dystrophy 21, also known as retinal dystrophy with early macular involvement, is related to cone-rod dystrophy 16 and cone-rod dystrophy 2. An important gene associated with Cone-Rod Dystrophy 21 is DRAM2 (DNA Damage Regulated Autophagy Modulator 2). The drug Liver Extracts has been mentioned in the context of this disorder. Affiliated tissues include bone and liver, and related phenotypes are photophobia and nyctalopia
