However, the analysis of an isocoding polymorphism 20 base pairs away and closely linked microsatellite markers in the patient and family members indicated that the 2 mutant alleles are unlikely to be identical by descent and that the 2 relatives fortuitously had RP and a mutation in the same codon of the USH2A gene.
