Comparative map of Naip array in mice of the 129 and C57BL/6J haplotypes. A summary of physical maps constructed in two different inbred mouse strains is indicated. Conserved gene loci are indicated by common colors. Repeat microsatellite markers identify a quadruplication in mice of the 129 lineage and a duplication in the C57BL/6J haplotype. Gray shading indicates the two complete and two partial Naiploci specific to the 129 haplotype. A hypothetical insertion point between Naip5 and ΔNaip in the C57BL/6J haplotype is indicated (see Discussion). The genetically mapped Lgn1interval is indicated in the C57BL/6J haplotype. Two open boxes indicate the positions of two recombination hot spots identified in ourLgn1 backcross.
