We determined 21 different mutations in PGM1 in 19 patients. Although all the patients acquired multisystem disease at the proper time of the study, the only apparent scientific feature at birth was a bifid uvula . Extensive usage of common protein polymorphisms of phosphoglucomutase 1 in paternity testing led to the discovery of a case of decreased enzyme activity in 1963, and since that time additional cases of reduced phosphoglucomutase 1 activity have already been defined sporadically.8,17-22 In 2009 2009, data on a grown-up with exercise-induced muscle tissue cramps and episodes of rhabdomyolysis were reported.2 Abnormal glycogen accumulation was noted in the muscle groups, the level of phosphoglucomutase 1 activity was only 1 percent of the normal level, and mutations in PGM1 were identified.Although results from studies in animals show that vitamin A can be an important determinant of early lung development and size, data are lacking on the long-term outcomes of vitamin A deficiency on lung wellness in human populations. We studied the effect of antenatal vitamin A supplementation on the lung function of preadolescent kids in a chronically undernourished human population in rural Nepal. The scholarly study cohort consisted of children, 9 to 13 years, whose mothers acquired participated in a randomized, placebo-controlled trial of vitamin A or beta-carotene supplementation before, during, and after pregnancy.
