Filaggrin gene mutations in relation to contact allergy and hand eczema in adolescence
Background Filaggrin is an important protein for structure and function of the skin barrier. Filaggrin gene (FLG) mutations are known to result in dry skin, impaired skin barrier, and increased risk for atopic dermatitis. However, it is not clear whether these mutations are associated with contact a...

Summary: | Background
Filaggrin is an important protein for structure and function of the skin barrier. Filaggrin gene (FLG) mutations are known to result in dry skin, impaired skin barrier, and increased risk for atopic dermatitis. However, it is not clear whether these mutations are associated with contact allergy or hand eczema in adolescence.
Objectives
The purpose of this study was to investigate whether FLG mutations are associated with contact allergy, self‐reported hand eczema, or dry skin in adolescence.
Methods
We used data from the 16‐year follow‐up in the BAMSE cohort, information obtained from a Web‐based questionnaire including questions on hand eczema and dry skin, from FLG mutation analysis (R501X, R2447X, 2282del4), and patch testing (n = 1822).
Results
Logistic regression analyses showed no statistically significant associations between FLG mutations and contact allergy (any contact allergy, nickel allergy, or fragrance allergy) according to patch test, or self‐reported hand eczema at 16 years, or hand eczema ever. However, FLG mutations were associated with self‐reported dry skin at 16 years.
Conclusions
FLG mutations are associated with self‐reported dry skin at 16 years. However, in this study no consistent associations were found between FLG mutations and contact allergy or hand eczema at 16. |
