title: Physical mapping of the pink-eyed dilution complex in mouse chromosome 7 shows that Atp10c is the only transcript between Gabrb3 and Ube3a.
abstract: Phenotypic analyses of a set of homozygous-lethal deletion mutants at the pink-eyed dilution (p) locus has resulted in the identification of p-linked obesity locus 1 (plo 1), distal to the p locus, as a locus involved in the modulation of body fat and/or affecting lipid metabolism in these mice. The plo 1 region maps to mouse chromosome 7 (MMU 7) between two genes, Gabrb3 and Ube3a, which have been used as anchor points to generate an integrated deletion and physical map of plo 1 that encompasses about 1.2-1.3 Mb. A deletion/physical map was constructed and the genomic DNA between the two loci was sequenced to identify genes mapping to this region. Data show that Atp10c, a novel type IV ATPase a putative phospholipid transporter, is the only coding unit in this region of the chromosome.
