Summaries for Carnitine Palmitoyltransferase Ii Deficiency, Myopathic,...

OMIM : 56 Carnitine palmitoyltransferase II deficiency is an inherited disorder of mitochondrial long-chain fatty acid oxidation. The myopathic form presents most frequently in children or young adults with muscle pain with or, in most cases, without myoglobinuria with elevation of serum creatine kinase precipitated by strenuous exercise, cold, fever, or prolonged fasting. Severity of attacks is highly variable. Myoglobinuria can cause kidney failure and death (summary by Deschauer et al., 2005 and Longo et al., 2006). See also the lethal neonatal (608836) and infantile (600649) forms of the disorder, which are also caused by mutation in the CPT2 gene. (255110)

MalaCards based summary : Carnitine Palmitoyltransferase Ii Deficiency, Myopathic, Stress-Induced, is also known as carnitine palmitoyltransferase ii deficiency, adult-onset, and has symptoms including myalgia, muscle cramp and muscular stiffness. An important gene associated with Carnitine Palmitoyltransferase Ii Deficiency, Myopathic, Stress-Induced is CPT2 (Carnitine Palmitoyltransferase 2). Affiliated tissues include kidney and skeletal muscle, and related phenotypes are muscle weakness and myopathy

UniProtKB/Swiss-Prot : 73 Carnitine palmitoyltransferase 2 deficiency, myopathic, stress-induced: An autosomal recessive disorder of mitochondrial long-chain fatty acid oxidation, characterized by recurrent myoglobinuria, episodes of muscle pain, stiffness, and rhabdomyolysis. These symptoms are exacerbated by prolonged exercise, fasting, cold, or viral infection. CPT2DM affects most frequently children or young adults, and severity of attacks is highly variable. Myoglobinuria can cause kidney failure and death.
