Mutation detailsA G to A transition at the end of exon 8 results in a G406R mutation which appears to be a gain of function mutation that is embryonic lethal in both hetero- and homozygotes. The insertion of an FRT:loxP flanked-inverted Neo cassette 301 bp downstream of the G->A point mutation introduces a stop codon in alternative exon 8A (which is mutually exclusive with exon 8) and ameliorates the lethality of the point mutation in heterozygotes.
