Below is an instruction from Human. Write a response.
    ### Instruction:
    What are the genetic changes related to carnitine palmitoyltransferase I deficiency ?
    ### Response:
    Mutations in the CPT1A gene cause CPT I deficiency. This gene provides instructions for making an enzyme called carnitine palmitoyltransferase 1A, which is found in the liver. Carnitine palmitoyltransferase 1A is essential for fatty acid oxidation, which is the multistep process that breaks down (metabolizes) fats and converts them into energy.
