Abstract
Carrier detection and prenatal diagnosis of Norrie disease (ND) were performed using the polymorphic L1.28, OTC, and 58-1 probes. L1.28 was polymorphic in 3 of the 5 ND families tested and informative in 2 families (40%). Probe 58-1 and OTC were informative in one of 3 families (33%) and in both of the 2 families (100%) tested, respectively. The major allele frequency was 73% in L1.28 (DXS7), 89% in 58-1 (DXS14), and 50% in OTC in our patient population. One of 5 families studies showed a recombination between probes (L1.28 and OTC) and the ND gene locus placing the ND locus proximal to L1.28 and OTC.
