Strain of Origin: WK/ReJ
Mutation
description
Allele Type: Spontaneous
Mutation: Single point mutation
  The G to A mutation in a splice site consensus sequence causes abnormal splicing and expression of multiple mRNAs. One mRNA is translated into an alpha 2 polypeptide with a deletion in domain VI. (J:21367, J:25954)
Inheritance: Recessive
