Through neonatal screening and case review, four patients with NICCD who had an acylcarnitine profile during infancy were all found to have an elevation of free carnitine, C2-carnitine, and long-chain acylcarnitines. These metabolic abnormalities appeared after the rise of citrulline and bilirubin, but before the elevation of alanine aminotransferase and aspartate aminotransferase. Although the rise of free carnitine and acylcarnitines seems to be a benign condition, the sequential changes of these metabolic derangements may give clues to the pathogenesis of this interesting disorder. ?
