Notes
Homozygous mutant mice died during the peri-implantation stage.

In contrast, homozygous mutant mice carrying Tg(SMN2)1Hung display pathological changes in the spinal cord and skeletal muscles similar to those of patients with proximal spinal muscular atrophy (SMA). Some of these mice do not develop hairy fur, and die before postnatal day 10. Others exhibit poor activity and variable symptoms, and die at approximately 2-4 weeks. A third group of these mice survive to adulthood and are fertile, but have short enlarged tails. The variable severity of the pathological changes in these mice correlates with transgene copy number and the amount of protein that contains the region encoded by exon 7.
