Carnitine Palmitoyl Transferase Deficiency
Type II (CPT-II)
A Fatty-acid Oxidation Disorder
What is it?
Carnitine Palmitoyl Transferase Deficiency Type II (CPT-II) is a disorder in which the body cannot oxidize fatty acids
Inheritance and Frequency
The gene defect for CPT-II is an autosomal recessive genetic trait and is unknowingly passed down from generation to generation. This faulty gene only emerges when two carriers have children together and pass it to their offspring. For each pregnancy of two such carriers, there is a 25% chance that the child will be born with the disease and a 50% chance the child will be a carrier for the gene defect.
Signs & Symptoms
CPT-II affects males more than females and is more apparent in people with diabetes or malnutrition. Fasting may trigger symptoms. It usually becomes apparent in adults, but a more serious form affects children. The major symptoms of CPT-II are myalgia, fatigue, and reddish-brown urine.
Long Term Effects
Treatment
Treatment includes a diet low in proteins and fats and high in carbohydrates, adequate hydration, avoidance of fasting, and keeping warm. Carnitine supplementation may be effective.
