Gene Affected
Origin The rat showed abnormal hair texture and mammary gland hypoplasia was occurred in the WTC.ZI-Atrnzi colony at the National Cancer Center Research Institute in 1998. After elimination of zi allele, this strain has been maintained by sib mating and transferred to Kyoto Univ. in April 2002.
Strain characteristics Homozygous mutants show sparse fur, which is most prominent at 3–4 weeks of age, and small body size. Swh (Sparse and wavy) locus was mapped on Chr 17. In 2011, Kuramoto et al. identified a missense mutation in the Edaradd gene.
Breeding Conditions Both male and female homozygous rats are fertile but female homozygous rat cannnot take care of their pups well. Therefore heterozygous female and homozygous male are mated.
