A number sign (#) is used with this entry because of evidence that retinitis pigmentosa-85 (RP85) is caused by homozygous mutation in the AHR gene (600253) on chromosome 7p21. One such family has been reported.

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

Clinical Features

Zhou et al. (2018) studied 2 distantly related Indian boys with retinitis pigmentosa, aged 8 years (RD-ICP-79) and 10 years (RD-ICP-78), from a large consanguineous family. Both boys reported early-onset progressive difficulty with night vision and gradually decreasing visual acuity bilaterally. Typical features of RP were observed in both patients, with fundi showing pigment deposits and a pale retina. OCT examination in patient RD-ICP-79 showed disorganized photoreceptor layers, and full-field electroretinography revealed severely reduced scotopic and photopic responses and oscillatory potentials in both eyes.

Molecular Genetics

In a large consanguineous Indian family in which 2 distantly related boys had RP, Zhou et al. (2018) performed whole-exome sequencing and identified homozygosity for a splice site mutation in the AHR gene (600253.0001) that segregated with disease and was not found in 1,000 ethnically matched controls or in the gnomAD database. In addition, no causal mutations were found in known RP genes.
