Strain description

The Cataract/Nakano mice are spontaneous mutants with hereditary cataract. The mice were derived from mice that Dr. Kenji Nakano discovered as spontaneous mutants with eye abnormalities in an inbred strain of mice with wa-1 and belt genes kept at the National Institute of Health in Tokyo (Ref. 1). The mode of inheritance is autosomal recessive. This hereditary cataract is caused by a hypomorphic mutation in the coproporphyrinogen oxidase (Cpox) gene (Ref. 2).
