Three recessive genes for congenital osteopetrosis in Norway rat

Three recessive genes for congenital osteopetrosis in Norway rat

R Moutier et al. J Hered. 1976 May-Jun.

Abstract

In the rat, the autosomal recessive toothless (t1) mutation exhibits an acute form of osteopetrosis. This gene is not an allele of either ia or op that causes respectively, a transitory and acute form of the disease. Comparative radiographic study of t1/t1 and op/op mutants reveals some differences in respect to the size and shape of long bones. In contrast to op/op mutants, homozygous t1/t1 animals failed to respond to either parabiosis or bone marrow transplants.
