Mutation detailsA neo cassette replaced the first exon, which contains the complete 5' UTR, start codon, signal peptide and the first LNS domain. Immunoblotting of mutant brain confirmed lack of protein expression. This knock-out affects the alpha isoform specifically. The beta isoform, transcribed from a downstream promoter, is not affected..
