This entry represents PCARE encoded by the C2ORF71 gene [, ]. Mutations of C2ORF71 has been associated with autosomal recessive (AR) retinitis pigmentosa (RP) in humans and with visual defects in zebrafish [, ]. The function of this family of proteins is unknown, but it is predominately expressed in the photoreceptors and is likely to be important in the development and function of the retina.
