A number sign (#) is used with this entry because of evidence that retinitis pigmentosa-61 (RP61) is caused by homozygous mutation in the CLRN1 gene (606397) on chromosome 3q25.

For a general phenotypic description and a discussion of genetic heterogeneity of retinitis pigmentosa (RP), see 268000.

Clinical Features

Khan et al. (2011) described 2 consanguineous Pakistani families segregating autosomal recessive retinitis pigmentosa. Analysis of the fundus of affected individuals of both families indicated attenuation of the retinal vessels, waxy appearance of the optic disc, and bone spicule pigmentation in the periphery of the retina. ERG analysis revealed that the scotopic responses, which are indicative of the activity of the rod photoreceptors, were more severely diminished than the photopic responses. The patients reported no hearing problems, and hearing impairment was ruled out by audiometric assessment in several patients.

Mapping

In 2 consanguineous Pakistani families segregating autosomal recessive retinitis pigmentosa, Khan et al. (2011) found linkage of RP to a region of chromosome 3p that encompassed the CLRN1 gene (606397). The CLRN1 gene is mutant in Usher syndrome type III (USH3; 276902), which includes retinitis pigmentosa as a feature.

Molecular Genetics

In affected members of 2 consanguineous Pakistani families segregating retinitis pigmentosa, Khan et al. (2011) identified homozygous missense mutations in the CLRN1 gene (606397.0009-606397.0010). The mutations were not found in 81 unrelated Pakistani RP patients or in 90 ethnically matched control individuals.
