[[http://www.uniprot.org/uniprot/CAH4_HUMAN CAH4_HUMAN]] Defects in CA4 are the cause of retinitis pigmentosa type 17 (RP17) [MIM:[http://omim.org/entry/600852 600852]]. RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP17 inheritance is autosomal dominant. Note=Defective acid overload removal from retina and retinal epithelium, due to mutant CA4, is responsible for photoreceptor degeneration, indicating that impaired pH homeostasis is the most likely cause underlying the RP17 phenotype.<ref>PMID:15563508</ref>
