The relationship between serum alkaline phosphatase (AP) isoenzymes, ABO blood groups and secretor phenotypes was evaluated in 125 Nigerian voluntary blood donors. The serum total AP activity patterns were group O > Group B > Group AB > Group A, but only the differences between A/B, A/O and AB/O were significant. The total and activities of the different isoenzymes were lowest in group A, while highest values were found in group O. The different activities for group AB were intermediate between the levels for A and B. The activities of the different isoenzymes tended to be higher in secretors than in non-secretors. Our results may suggest that both the blood group and secretor genes are strong determinants of AP isoenzyme patterns in Nigeria.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000017 ABO Blood-Group System The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane.

D000469 Alkaline Phosphatase An enzyme that catalyzes the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. EC 3.1.3.1.
D014508 Urea A compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids. Basodexan,Carbamide,Carmol
