Saliva acid phosphatases: genetic studies

S G Tan, G C Ashton

    Human Heredity
    |January 1, 1976
    PubMed
    Summary

    Human saliva contains acid phosphatases, with six identified phenotypes. Genetic analysis indicates these phenotypes result from two gene loci, Sap-A and Sap-B, each with specific alleles.

    Area of Science:

    • Biochemistry
    • Human Genetics
    • Enzymology

    Background:

    • Acid phosphatases are enzymes present in various human tissues, including saliva.
    • Understanding enzyme polymorphisms is crucial for genetic studies and diagnostics.

    Purpose of the Study:

    • To characterize the phenotypes of acid phosphatases in human saliva.
    • To investigate the genetic basis of these salivary acid phosphatase phenotypes.

    Main Methods:

    • Zymogram technique was employed to visualize and differentiate acid phosphatase phenotypes.
    • Family and population studies were conducted to analyze inheritance patterns.

    Main Results:

    • Six distinct acid phosphatase phenotypes were identified in human saliva.
    • The observed phenotypes are controlled by two genetic loci: Sap-A (alleles A, A', O) and Sap-B (alleles B, O).

    Conclusions:

    • Salivary acid phosphatases exhibit genetic polymorphism in the human population.
    • The inheritance of salivary acid phosphatase phenotypes follows Mendelian patterns controlled by two independent loci.
