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.
Breeding Conditions
Both, male and female rats are fertile. However heterozygous female and homozygous male are mated.
