In addition to causing polymalformative syndrome, 22q11.2 deletion can lead to various neuropsychiatric disorders including mental retardation, psychosis, and epilepsy. However, few reports regarding epilepsy-related psychosis in 22q11.2 deletion syndrome (22q11.2DS) exist. We describe the clinical characteristics and course of 22q11.2DS in a Japanese patient with comorbid mild mental retardati...

We found that proline oxidase, the first enzyme of the proline degradative pathway, is inhibited by lactate. The Km of the enzyme for proline increases with increasing concentrations of lactate. Since proline can be a source for gluconeogenesis, regulation of proline degradation by lactate may serve as a mechanism for allocation of metabolic fuel sources. The marked inhibition of proline oxidas...

Lately, microdeletions of the 22q region, responsible for DiGeorge syndrome or velocardiofacial syndrome, have been increasingly related to neuropsychiatric disorders including schizophrenia and bipolar disorder. These manifestations seem to be related to certain genes located in the hemideleted region such as the proline dehydrogenase (PRODH) and the catechol-o-methyltransferase (COMT) genes. ...

Proline metabolism is linked to hyperprolinemia, schizophrenia, cutis laxa, and cancer. In the latter case, tumor cells tend to rely on proline biosynthesis rather than salvage. Proline is synthesized from either glutamate or ornithine; both are converted to pyrroline-5-carboxylate (P5C), and then to proline via pyrroline-5-carboxylate reductases (PYCRs). Here, the role of three isozymic versio...
