The KCC1 K-Cl cotransporter is a major regulator of erythroid and non-erythroid cell volume, and the KCC1 gene is a candidate modifier gene for sickle cell disease and other hemoglobinopathies. We have cloned and sequenced the mouse KCC1 (mKCC1) gene, defined its intron-exon junctions, and analyzed (AC)/(TG) intragenic polymorphisms. A highly polymorphic (AC) repeat of mKCC1 intron 1 was characterized in musculus strains, and used to prove lack of linkage between the mKCC1 gene and the rol (resistant to osmotic lysis) locus. The intron 1 (AC) repeat in CAST/Ei and SPRET/Ei was not only more divergent in length but also underwent additional sequence variation. A dimorphic (TG) repeat in intron 2 distinguished CAST/Ei from other strains, and an intron 17 B1 Alu-like SINE present in all musculus strains was found to be absent from intron 17 in SPRET/Ei. These and additional described strain-specific polymorphisms will be useful mapping and genetic tools in the study of mouse models of sickle cell disease.
