Abstract:Gyrate atrophy (GA) is a rare degenerative, hereditary disease characterized by markedly high serum ornithine levels resulting from the deficiency of ornithine-delta-amino transferase (OAT), a mitochondrial matrix enzyme. Hyperornithinaemia is accompanied by lysinuria and reduced lysine plasma levels in GA. Type I collagen is known to play a role in osteoporosis pathogenesis. Lysine has a role in cross ligament formation of type I collagen, a bone matrix element, and thus, in bone strength. Although the most c… Show more
