Mutation detailsExon 7 was replaced with one in which a C to T transition, mimicking a muatation found in roximal spinal muscular atrophy (SMA) patients, results in exclusion of exon 7 from the premRNA. An FRT flanked neo cassette inserted upstream of exon 7 and removed by flp mediated recombination. Reduced protein expression was confirmed by western blot analysis on kidney, liver, brain, spinal cord, and quadricep extracts. (J:164889)
