Abstract
We report the molecular analysis of the beta subunit of the rod phosphodiesterase (PDEB) gene in a consanguineous autosomal recessive retinitis pigmentosa family that shows homozygosity for polymorphisms in the genomic region comprising this gene, and positive linkage between a PDEB marker and the disease. The two affected sisters are homozygous for a T to G transversion in codon 699 of the PDEB gene, leading to the substitution of a leucine by an arginine residue. This change, enclosed in the catalytic domain of the PDEB, could result in a modification of the protein structure preventing the physiological hydrolysis of cGMP.Entities:
