| Name | Hyperprolinemia |
| Description | Hyperprolinemia (HP) is a phenotype present in two distinct, autosomal recessive metabolic disorders caused by defects in the l-proline catabolic pathway. Hyperprolinemia type I (HPI) and type II (HPII) are caused by deficiencies in proline dehydrogenase (PRODH) and P5C dehydrogenase (P5CDH; also known as ALDH4A1), respectively. Patients with HPI may exhibit an increase in plasma proline level in absence of urinary pyrroline-5-carboxylate (P5C) while those with HPII have elevated levels of P5C and proline in plasma, urine, and cerebrospinal fluid. Some patients have neurological, renal, and/or auditory defects. |
