Daniels R J - - 1995
Autosomal recessive childhood onset spinal muscular atrophy has been mapped to chromosome 5q13. We report the analysis of a polymorphic microsatellite which shows linkage disequilibrium with the disease. The linkage disequilibrium is observed with a null allele which is seen as the non-inheritance of alleles from one or both parents. ...
Roy N - - 1995
The spinal muscular atrophies (SMAs), characterized by spinal cord motor neuron depletion, are among the most common autosomal recessive disorders. One model of SMA pathogenesis invokes an inappropriate persistence of normally occurring motor neuron apoptosis. Consistent with this hypothesis, the novel gene for neuronal apoptosis inhibitory protein (NAIP) has been ...
Bakker E - - 1995
Facioscapulohumeral muscular dystrophy (FSHD) has recently been shown to be associated with deletions that are detectable using probe p13E-11 (D4F104S1). Although these deletions reside within large, highly polymorphic restriction fragments (20-300 kb), the "mutant" fragment is usually shorter than 28 kb and can routinely be detected using conventional agarose gel ...
Lee J H - - 1995
Facioscapulohumeral muscular dystrophy (FSHD) is a dominantly inherited muscular disorder and the gene for FSHD has been mapped to chromosome 4q35. Recently, the DNA rearrangements associated with the disease were found in the EcoRI fragment detected by the probes p13E-11 and pFR-1, and deletions of the 3.3-kb KpnI repeat units ...
