Clinical Features

Gieser et al. (1998) described a 5-generation family with X-linked retinitis pigmentosa designated RP24. Affected males (hemizygotes) had early onset of rod photoreceptor dysfunction; cone-receptor function was normal at first, but there was progressive loss. Patients at advanced stages showed little or no detectable rod or cone function and had clinical hallmarks of typical RP.

Mapping

Gieser et al. (1998) demonstrated linkage of X-linked retinitis pigmentosa in a 5-generation family to Xq26-q27. A maximum lod score of 4.21 was obtained with DXS8106. Haplotype analysis assigned RP24 within a 23-cM region between the DXS8094 (proximal) and DXS8043 (distal) markers.

Clinical Management

Grover et al. (2000) evaluated the progression of visual impairment in carriers of X-linked recessive retinitis pigmentosa (XLRP). They described the relationship between retinal findings at presentation and the extent of subsequent deterioration. They followed visual acuity, visual field, and electroretinograms in 27 carriers of XLRP and described 4 grades of fundus findings from grade 0 (normal) to grade 3 (diffuse changes). They found that carriers of XLRP with only a tapetal-like retinal reflex (grade 1) at presentation were more likely to retain visual function than those with peripheral retinal pigmentation. Grover et al. (2000) concluded that these data are useful in counseling such carriers as to their visual prognosis.
