Dermatoglyphics in vitiligo.

S Iqbal, S Premalatha, A Zahra

    International Journal of Dermatology

    Summary
    This summary is machine-generated.

    Vitiligo patients show distinct dermatoglyphic patterns, including altered finger ridge counts and unique crease occurrences. These findings suggest potential genetic markers for vitiligo.

    Area of Science:

    • Dermatology
    • Genetics
    • Anthropology

    Background:

    • Vitiligo is a complex autoimmune disorder affecting skin pigmentation.
    • Palmar dermatoglyphics, the study of skin patterns on palms, can offer insights into genetic predispositions.
    • Previous research on dermatoglyphics in vitiligo is limited.

    Purpose of the Study:

    • To investigate qualitative and quantitative palmar dermatoglyphic differences between vitiligo patients and healthy controls.
    • To identify potential dermatoglyphic markers associated with vitiligo.

    Main Methods:

    • A case-control study involving 100 vitiligo probands and 100 healthy controls.
    • Qualitative analysis of dermatoglyphic patterns (e.g., ulnar loop, whorl, arch).
    • Quantitative analysis including total finger ridge count (TFRC), a-b ridge count, and atd angle.

    Main Results:

    • Ulnar loop was the predominant pattern in both groups.
    • Significantly higher incidence of whorls in male vitiligo patients and arches in female vitiligo patients compared to controls.
    • Statistically significant reduction in TFRC and a-b ridge count observed in vitiligo cases.
    • Novel observations of Simian crease and Sydney line in vitiligo patients.

    Conclusions:

    • Palmar dermatoglyphics reveal significant differences in vitiligo patients, particularly in ridge counts and pattern frequencies.
    • The presence of Simian crease and Sydney line in vitiligo warrants further investigation.
    • Dermatoglyphic patterns may serve as potential, albeit not definitive, indicators in vitiligo research.
