  • Title: Familial recurrent rhabdomyolysis due to carnitine palmityl transferase deficiency.
    Author: Patten BM, Wood JM, Harati Y, Hefferan P, Howell RR.
    Journal: Am J Med; 1979 Jul; 67(1):167-71. PubMed ID: 463910.
    Abstract:
    Muscle carnitine palmityltransferase (CPT) activity was very low (0 to 14 per cent of controls) in two brothers with a syndrome of recurrent rhabdomyolysis and myoglobulinuria. In isolated muscle mitochondria the majority (87.5 per cent) of total measurable CPT enzyme activity could be attributed to external membrane CPT with severe deficiency of inner membrane CPT. By contrast, control mitochondria demonstrated a 1:1 distribution of external membrane CPT to inner membrane CPT. Thus, myoglobinuria may be due to a genetic defect of lipid metabolism in skeletal muscle, with inner membrane CPT deficiency presenting the same clinical features as external membrane CPT deficiency.
