Molecular Genetics

By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Inaba et al. (1996) showed in a population of Japanese Black cattle, that this disorder is due to a nonsense mutation (CGA>TGA; Arg>Stop) in the gene for band 3 of red cell membrane, at the position corresponding to codon 646 of the human gene. The lack of this protein produces very unstable red-cell membranes, resulting in anaemia and retarded growth.
