A novel locus (RP24) for X-linked retinitis pigmentosa maps to Xq26-27.
Two genetic loci, RP2 and RP3, for X-linked retinitis pigmentosa (XLRP) have been localized to Xp11.3-11.23 and Xp21.1, respectively. RP3 appears to account for 70% of XLRP families; however, mutations in the RPGR gene (isolated from the RP3 region) are identified in only 20% of affected families. Close location of XLRP loci at Xp and a lack of unambiguous clinical criteria do not permit assign...
متن کاملA novel locus for X-linked retinitis pigmentosa.
INTRODUCTION Retinitis pigmentosa (RP) is the most prevalent group of inherited retinopathies and demonstrates considerable clinical and genetic heterogeneity, with wide variations in disease severity, progression, and gene involvement. We studied a large family with RP to determine the pattern of inheritance and to identify the disease-causing gene/locus. MATERIALS AND METHODS Ophthalmic exa...
متن کاملX-linked retinitis pigmentosa.
Of 107 consecutive patients with genetically-determined retinitis pigmentosa, 23 were provisionally diagnosed as having inherited the disease in an X-linked fashion. 42 affected males and 61 females were examined, and from the data obtained the following conclusions were drawn: (1) X-linked retinitis pigmentosa exists and is distinct from choroideremia. (2) In contrast to the results of previou...

متن کاملA retinitis pigmentosa GTPase regulator (RPGR)-deficient mouse model for X-linked retinitis pigmentosa (RP3).
The X-linked RP3 locus codes for retinitis pigmentosa GTPase regulator (RPGR), a protein of unknown function with sequence homology to the guanine nucleotide exchange factor for Ran GTPase. We created an RPGR-deficient murine model by gene knockout. In the mutant mice, cone photoreceptors exhibit ectopic localization of cone opsins in the cell body and synapses and rod photoreceptors have a red...
