Name: Medically supervised fastingDescription: Metabolic fasting studies will be conducted over an 18-hour period or until blood glucose is < 40 mg/dl. If the YSI reading is 40 mg/dl or less, at any time during the study, then a blood sample will be collected, and the fast terminated by giving D25W IV and then feeding orally.Type: Other
Single Group Assignment
There is one SNP
All of the infants are homozygous for a c.1436C-T sequence variant in the CPT1A gene, which results in the substitution of a leucine for proline at amino acid position 479 (P479L), and an approximately 80% reduction of CPT1A activity (non-classic CPT1A deficiency) (7). --- P479L ---
