Alternative titles and symbols : Proline oxidase deficiency; HPI;
Description : Phang et al. (2001) noted that prospective studies of HPI probands identified through
newborn screening as well as reports of several families have suggested that it is
a metabolic disorder not clearly associated with clinical manifestations. Phang et
al. (2001) concluded that HPI is a relatively benign condition in most individuals
under most circumstances. However, other reports have suggested that some patients
have a severe phenotype with neurologic manifestations, including epilepsy and mental
retardation (Jacquet et al., 2003).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the proline dehydrogenase gene (PRODH, 606810.0001);
