Gene: [19q131/GPI] glucosephosphate isomerase (phosphohexose isomerase); phosphoglucose isomerase (phosphohexose isomerase); anemia hemolytic nonspherocytic (GPI deficiency);
TIS |
Tissue-specific forms of glucosephosphate isomerase (GPI) are not yet revealed, and so the reason for selective leison of red blood cells in the hereditary GPI deficiencies is not clear. Blume-1972 described a simple method of scrining for GPI deficiency." |

[1] When a genetic defect is present, the decrease in glucosephosphate
isomerase (GPI) activity is found in all organs and tissues. But the
morphofunctional defects do not occur in nonerythroid cells, the only
manifestation of mild GPI deficiencies consists in more or less
pronounced nonspherocytic hemolytic anemia (Baughan-1968). In some
cases, the destruction of red blood cells decreases with age
(Hutton-1974). Spleen ablation may weaken the hemolisis
though not completely eliminate it completely (Paglia-1969,
Matsumoto-1973).
[2] Schroter-1985 described a case of the generalized GPI deficiency (GPI-Homburg), which clinical manifestations included, in addition to recurrent spontaneous hemolitic crises, neuromuscular lesions (myasthenia, sensitive and cerebellar ataxia), mental retardation, and deecreased immunity. A number of fetal hydrops cases were also described (this rarely the case in erythrocitic enzymopathies); in addition, there was a case of early neonatal death in an Indian family, hemolitic anemia in the survived proband being related with GPI deficiency (Ravindranath-1987)." |
