When only the 28 animals that died during transport or isoflurane challenge were classified as affected in the analysis, a similar but less significant association was found with the same markers at the dystrophin locus (p < 2 x 10-11).The two most significant SNPs on the beadchip (ALGA0099513 and ALGA0099514) are located within intron 44 of the dystrophin gene (DMD). The gene discussed is DMD; the disease is Duchenne muscular dystrophy.
