Abstract
A newly identified human locus on chromosome 15 was recently associated with zinc accumulation. Based on a prior report of a threefold difference in zinc accumulation between fumble1 heterozygous mutants and control fly strains, it was suggested that phosphopantothenoylcysteine decarboxylase might affect zinc status through its effects on vitamin B5 (pantothenate) metabolism. We report here that outcrossed fumble1 heterozygous mutant flies with low zinc content have been recovered, suggesting that pantothenate metabolism did not alter zinc homeostasis in fumble1 heterozygous flies. We show instead that the Drosophila condition of low body zinc accumulation is an X-chromosome-linked recessive trait.
Flies with a threefold reduction in zinc accumulation remain viable and fertile.
There is no causal association between zinc accumulation and fly pantothenate kinase mutants.
A widespread X-linked mutation causes a threefold reduction in zinc accumulation in Drosophila.
