Delineation of the critical interval for the familial exudative vitreoretinopathy gene by linkage and haplotype analysis (original) (raw)

Abstract.

Familial exudative vitreoretinopathy (FEVR) is an ocular disorder characterized by deficient vascularization of the peripheral retina and causes visual loss attributable to various types of retinal detachment. The locus of the gene responsible for the autosomal dominant form of FEVR (EVR1) has been assigned to 11q13–23. However, a detailed evaluation of the critical region has not been made. We present the results of linkage analysis of the EVR1 locus on 11q13–23 in 43 individuals belonging to seven unrelated families of Japanese origin. Multi-point analysis has shown that six families out of the seven are linked with 11q13–23 markers. Haplotype analysis reveals that the putative region is probably flanked by polymorphic markers D11S1362 and CHLC.GATA30G01, which are approximately 200 kb apart, although the recombination events in small families such as presented in this study should be interpreted cautiously.
