چکیده

PURPOSE To report a novel missense mutation in the XLRS1 gene in a Korean family with X-linked retinoschisis. METHODS Observation case report of a family with a proband with X-linked retinoschisis underwent complete ophthalmologic examination. Genomic DNA was excluded from the family's blood and all exons of the XLRS1 gene were amplified by polymerase chain reaction and analyzed using a direct sequencing method. RESULTS A novel Leu103Phe missense mutation was identified. CONCLUSIONS A novel Leu103Phe mutation is an additional missense mutation which is responsible for the pathogenesis of X-linked retinoschisis.

Mutational Screening of RS1 gene in X-linked Retinoschisis in an South Indian Family

Purpose: To screen XLRS1 gene for genetic mutations and describe the ocular phenotypes in an X-Linked retinoschisis family. Methods: Ophthalmic examination, including best-corrected visual acuity, fundus photography, Ocular Coherence Tomography/Scanning Laser Ophthalmoscopy (OCT/SLO) and full-field Electroretinography (ERG) was performed in the family. Pedigree was obtained and peripheral blood...

Electroretinographic findings in three family members with X-linked juvenile retinoschisis associated with a novel Pro192Thr mutation of the XLRS1 gene.

PURPOSE To present ocular findings in three family members with X-linked juvenile retinoschisis (XLRS) associated with a novel Pro192Thr mutation. CASES We examined 21- (Case 1), 17- (Case 2), and 10-year-old (Case 3) male patients who showed wheel-like cystic lesions in the macula and a silver-gray reflex in the peripheral retina. Case 2 was a cousin of Case 1. Case 3 was a brother of Case 2...

Novel mutations in XLRS1 causing retinoschisis, including first evidence of putative leader sequence change.

Juvenile retinoschisis is an X-linked recessive disease caused by mutations in the XLRS1 gene. We screened 31 new unrelated patients and families for XLRS1 mutations in addition to previously reported mutations for 60 of our families (Retinoschisis Consortium, Hum Mol Genet 1998;7:1185-1192). Twenty-three different mutations including 12 novel ones were identified in 28 patients. Mutations iden...

Molecular analysis of the XLRS1 gene in 4 females affected with X-linked juvenile retinoschisis.

BACKGROUND X-linked juvenile retinoschisis (XLRS) is the most common cause of juvenile macular degeneration in males. Because of its X-linked mode of transmission, the disease is rare in females. In this article, we describe a mutation screen conducted on a family in which 4 female patients affected with XLRS presented with an unusually severe phenotype. METHODS DNA was extracted from periphe...

X-linked retinoschisis with point mutations in the XLRS1 gene.

BACKGROUND X-linked retinoschisis (XLRS) is a relatively rare vitreoretinal dystrophy that causes visual loss in young men. Recently, a gene responsible for this disease, designated XLRS1, was identified, and several deleterious gene mutations were reported. OBJECTIVE To analyze Japanese patients clinically diagnosed as having XLRS formutational changes in the XLRS1 gene. METHODS Ten patien...
