A study of 6-PGD in the population of Rome. 6-PGD phenotype was determined by starch gel electrophoresis in 268 subjects from the population of Rome. PGD end PGD gene frequencies were 0.994 and 0.006 respectively.
Control of fetal genotype on the placental PGM phenotype. Simultaneous analysis of PGM phenotype on placental tissue and on red cells from newborn babies and their mothers has shown that the electrophoretic phenotype of placental PGM is under the control of fetal genotype only.
Erythrocyte acid phosphatase activity in red blood cells from newborn babies and their mothers. Erythrocyte acid phosphatase activity in red blood cells of newborn babies is lower compared to the activity found in their mothers. The difference seems to be dependent on the phenotype of acid phosphatase.
È stato determinato il fenotipo della fosfatasi alcalina della placenta e della fosfoglucomutasi in un gruppo di soggetti della provincia di Pavia. Le frequenze geniche relative alla fosfoglucomutasi, locus 1, non sono risultate differenti da quelle osservate nelle altre popolazioni italiane, mentre per la fosfatasi alcalina placentare sono state osservate alcune differenze. Sono stati inoltre individuati sei fenotipi rari per la fosfatasi alcalina placentare.
