abstract：:Copper incorporation studies were performed on individuals from 58 pedigrees, comprising 140 sibships. As previously reported, there is considerable overlap between heterozygotes and normal homozygotes. Segregation analysis supports recessive inheritance of disease, with residual heritability for 64Cu uptake in cultur...
