14bp deletion in the intron, and a base change of the first nucleotide of the intron (G to A).
14 bp deletion; one of two lesions associated with the allele.
G19250101A
Splice donor mutation; G to A change in the first base of the intron; one of two lesions associated with the allele.
Embryos derived from homozygous females are weakly dorsalised and fail to hatch. Transheterozygotes with wblRP, wblM46, wblT6 or wblE4 also have reduced viability, and embryos derived from these transheterozygous females are dorsalised and fail to hatch. wblM88/wblAR51 transheterozygotes have reduced viability, and approximately 99% of embryos laid by wblM88/wblAR51 females hatch.
