Congenital retinoschisis (RS) is a hereditary eye disorder characterized by intraretinal schisis and central and peripheral retinal lesion. The gene responsible for the X-linked retinoschisis (XLRS1) has recently been isolated and found to contain mutations in affected members of several families.
A missense mutation in the mouse Col2a1 gene has been discovered, resulting in a mouse phenotype with similarities to human spondyloepiphyseal dysplasia (SED) congenita. In addition, SED patients have been identified with a similar molecular mutation in human COL2A1. This mouse model offers a useful
OBJECTIVE
We identified a large Chinese family with X-linked juvenile retinoschisis. The purpose of this study was to report the clinical findings of the family and to identify the genetic mutation by screening the retinoschisis 1 (RS1) gene.
METHODS
Family history was collected and all family
OBJECTIVE
To present an Arg213Trp missense mutation in the XLRS1 gene in a family with juvenile X-linked retinoschisis in which one affected male had a normal electroretinogram scotopic b-wave amplitude.
METHODS
Two affected males and one unaffected male from this family with X-linked retinoschisis
X-linked retinoschisis (XLRS) is a vitreo-retinal degeneration caused by mutations in the RS1 gene which encodes the protein retinoschisin (RS1), required for the structural and functional integrity of the retina. Data are presented from a group of 38 XLRS patients from Moorfields Eye Hospital
