  Smn1	(MGI:109257)

• Mutation details: A 115 kb genomic fragment from a BAC clone containing the entire human SMN2 and SERF1A genes, and part of BIRC1, was used as the transgene. Transgenic animals were identified by PCR genotype analysis. (J:59313)

Notes

Five lines were generated.

Hemizygous transgenic mice that are also homozygous for Smn1^tm1Hung display:

• a range of spinal muscular atrophy (SMA)-like pathologies characterized as type 1, type 2, and type 3
  • Type 1 animals do not develop hairy fur, and die before postnatal day 10
  • Type 2 animals exhibit poor activity and variable symptoms, and die at approximately 2-4 weeks
  • Type 3 animals survive to adulthood and are fertile, but have short enlarged tails

• Transgene copy number correlates with the amount of protein that contains the region encoded by exon 7 and the severity of SMA-like phenotypes in these animals
