    Slow acetylation phenotype, a metabolic trait, was not found to correlate with lighter skin complexions in Caucasians. This suggests acetylation of carcinogens may not be a primary factor in melanoma risk.

    Area of Science:

    • Pharmacogenetics
    • Dermatology
    • Toxicology

    Background:

    • Acetylation phenotype influences drug and xenobiotic metabolism.
    • Melanoma risk is multifactorial, potentially involving genetic and environmental factors.
    • Skin complexion is a known risk factor for melanoma.

    Purpose of the Study:

    • To investigate the association between acetylation phenotype and skin complexion in Caucasians.
    • To determine if slow acetylation is linked to lighter skin, a melanoma risk factor.
    • To evaluate the role of xenobiotic carcinogen acetylation in melanoma risk.

    Main Methods:

    • 155 healthy Caucasian individuals participated in the study.
    • Participants received 500 mg of sulphadimidine.
    • Urine samples were collected 8 hours post-administration and analyzed for acetylated sulphadimidine percentage using high-performance liquid chromatography.

    Main Results:

    • A slight, statistically insignificant trend towards more slow acetylators was observed in darker skin types.
    • No significant correlation was found between slow acetylation phenotype and light skin complexion.
    • The findings did not support a link between acetylation status and skin type.

    Conclusions:

    • Slow acetylation phenotype is not associated with light skin complexion in the studied population.
    • The acetylation of xenobiotic carcinogens is unlikely to be a dominant factor in determining melanoma risk.
    • Further research may explore other genetic or environmental factors influencing melanoma development.
