OMIA 000060-9940 : Argininaemia in Ovis aries
Possibly relevant human trait(s) and/or gene(s) (MIM number): 207800 Mendelian trait/disorder: yes Considered a defect: yes Key variant known: no Cross-species summary: Deficiency of the enzyme arginase in red blood cells. The enzyme's normal task is to convert arginine to ornithine and urea Species-specific description: Homozygotes for the deficiency have zero levels of arginase; heterozygotes appear to have somewhat lower levels than homozygote normals (Wright et al., 1977). In contrast to humans, deficient sheep show no clinical signs, despite having elevated levels of arginine in red blood cells.
