| molecularNote | Exon 7 was replaced with one in which a C to T transition at position 6 of this exon. A floxed pgk-neo selection cassette was inserted about 180 bp distal to exon 7 in the antisense orientation. Analysis of protein expression indicates very low levels of Smn1 and that this is a hypomorphic allele. |
