Notes

A possible effect of the mutation in heterozygotes (Cacna1s^mdg/+) was discovered by Atchley et al. (J:7655), who found that the dimensions and shape of the mandible showed greater right-left asymmetry in Cacna1s^mdg/+ than in +/+ mice and that the parts of the mandible affected were those with most extensive muscle attachment.
