Abstract
To assess the contribution of TULP1 to autosomal recessive retinitis pigmentosa (arRP). Fifteen exons of the gene were screened by single-strand conformation polymorphism analysis of 7 (of 49) arRP pedigrees showing cosegregation with TULP1 locus markers. In one of the seven families two allelic mutations, IVS4-2delAGA and c.937delC, were found in exons 5 and 10, respectively. Two novel mutations in TULP1 were found to be associated with arRP. That they both compromise the gene product supports their pathogenicity. This gene was present in no more than 2% of a panel of 49 Spanish families affected by arRP.
