The linkage relationship between the locus for juvenile retinoschisis (RS) and four X-chromosomal marker loci DXS9 (RC8), DXS16 (XUT23), DXS41 (99-6), and DXS43 (D2) has been studied in six families showing a history of this disease. Recombination with RS was found for all marker loci except DXS9. The maximum lod score is zeta = 2.66 for RS vs. DXS9 at a recombination fraction of theta = 0.0. Multipoint linkage analysis was performed and the locus order best supported by our data is: RS - DXS9 - DXS43 - DXS16 - DXS41.

D012150 Polymorphism, Restriction Fragment Length Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment. RFLP,Restriction Fragment Length Polymorphism,RFLPs,Restriction Fragment Length Polymorphisms
D012163 Retinal Detachment Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.
