OMIA 000818-9940 : Potassium transport in Ovis aries

Mendelian trait/disorder: yes

Considered a defect: yes

Key variant known: no

Species-specific description: An autosomal polymorphism of high potassium and low sodium (HK) versus low potassium and high sodium (LK) in red blood cells has long been recognised in sheep, with LK being dominant or incompletely dominant to KH (Evans and King, 1955). Despite many searches in many populations, there is no convincing evidence of associations between this polymorphism and productivity (Ellory and Tucker, 1983). There is, however, quite strong evidence that this polymorphism is actually the M blood group system, with the L factor (now called Mb) at this locus being an inhibitor of potassium transport into the cell (Bell, 1983).
