Genetic and physical location of the gene for Stargardt`s disease and further evidence for genetic homogeneity

Stargardt`s disease is inherited as an autosomal recessive condition characterized by a juvenile macular dystrophy. Genetic linkage analysis recently assigned the disease locus to chromosome 1p21-p13 with the best estimate for location of the gene near the locus D1S435. We performed linkage analysis in 34 North American families and 2 inbred families from the Kingdom of Saudi Arabia with 12 highly…
