title: Maternal treatment with teratogen causes congenital malformations in mouse embryos.
abstract: Heterozygotes for the tail-short (Ts) mutant gene in the Balb/c strain have minor skeletal defects and a short, kinky tail. If heterozygote Ts/+ mothers are mated with normal-tail +/+ males and are treated with teratogenic doses of trypan blue on the eighth day of pregnancy, the mutant F1 heterozygotes develop exencephaly, folded neural tube and spina bifida significantly more often than non-mutants. This is indicative of gene-teratogen interaction, with the Ts gene increasing the embryo's susceptibility to trypan blue-induced neural tube defects.
