A serine-to-proline mutation in the copper-transporting P-type ATPase gene of the macular mouse.
We have investigated the cDNA sequence of the copper-transporting P-type ATPase (Atp7a) gene of the macular mouse, a model for human Menkes disease. A point mutation (T to C) that results in substitution of proline for serine in a putative eighth transmembrane domain of the ATP7A was identified. This contrasts with abnormalities identified in the Atp7a of other mottled mouse strains: lack of expression of Atp7a mRNA in the dappled mouse, and a splicing mutation in the blotchy mouse.
