| Identified Mutation |
PRO23HIS; Dryja et al. [New Eng. J. Med. 323:1302 (1990)] were prompted to study the rhodopsin gene is cases of retinitis pigmentosa because the gene maps to the sane region of 3q where a form of retinitis pigmentosa was found to map in an Irish kindred (180100) and because rhodopsin is expressed in rod photoreceptors that are affected early in retinitis pigmentosa. In 17 of 148 unrelated patients and none of 102 unaffected individuals, Dryja et al. [New Eng. J. Med. 323:1302 (1990)] found a C-to-A transversion in codon 23 (corresponding to a proline-to-histidine substitution). |
| Remarks |
Son is also affected; dominant sector RP; 20 year history of photosensitivity; subnormal photopic ERG; inferior & nasal retinal degeneration with sparse pigmentation; C to A transversion in exon 1, codon 23, of the RHO (rhodopsin) gene [Pro23His (P23H)] |
