| Allelic Variant 1 |
603937.0001; RETINITIS PIGMENTOSA 1 |
| Identified Mutation |
ARG677TER; In a patient with autosomal dominant retinitis pigmentosa (180100), Pierce et al. (Nat Genet 22:248-254, 1999) found a C-to-T transition in exon 4 of the RP1 gene, resulting in a nonsense mutation, CGA (arg) to TGA (ter). This mutant allele, if expressed, would encode a protein of 676 amino acids, 1,480 less than the predicted wildtype RP1 protein. The mutation was first identified in the family in which Blanton et al. (Genomics 11:857-869, 1991) identified linkage to chromosome 8. |
| Remarks |
Clinically affected; spouse of GM10533; affected daughter is GM09775; donor subject has a C>T transition at nucleotide 2029 in exon 4 of the RP1 gene [2029C>T] resulting in a substitution of a stop codon for arginine at codon 677 [Arg677Ter (R677X)].
