X-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...
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 کاملElectroretinographic testing as an aid in detection of carriers of X-chromosome-linked retinitis pigmentosa.
Twenty-two of 23 obligate female carriers in nine families with known X-chromosome-linked retinitis pigmentosa were detected on the basis of abnormal full-field electroretinograms (ERGs). Only 14 of these carriers had fundus findings characteristic of the carrier state. Electroretinograms of carriers were either reduced in amplitude to white light under dark-adapted conditions or delayed in con...
