Major hyperpipecolataemia in a normal adult.
We describe the fortuitous discovery of a 44-year-old man with a very high hyperpipecolataemia (250 mumol/L; normal < 2.5). This patient has none of the clinical features seen in peroxisomal diseases, he is a strictly normal intelligent adult. A stereochemical study of this pipecolic acid was performed using D-amino acid oxidase, and identified it as L-pipecolic acid. We suggest that isolated L-hyperpipecolataemia may be a benign trait.
