| abstractText | Pregnant mice congenic with C57BL/10 (B10.A, B10.BR, B10.D2, B10.A[2R], B10.A[5R], B10.A[15Rd, B10.A[1R], B10.A[18R], and B10.0L) were fed Purina Mouse Chow or the same diet plus 200 IU of vitamin A daily. The pregnant dams were sacrificed on the eighteenth day of gestation, and the fetuses were sexed and examined for defects in neural tube development. The frequency of neural tube defects was low (mean frequency of all strains, 0.36%) and was not affected by the addition of vitamin A (200 IU/day) to the diet. Twenty-seven of the 29 defects observed occurred in the anterior tube (exencephaly); fourteen were identified in female fetuses, but the sex could not be determined in the other 15 cases because of fetal death and early autolysis. Variations in frequency among the strains suggest that a locus between E beta and H-2D has a moderate influence on the occurrence of neural tube defects. Strains that had H-2d alleles in this segment of the H-2 complex had relatively high frequencies, and those with H-2b or H-2k alleles had significantly lower frequencies. |
