Association of filaggrin gene polymorphism with atopic dermatitis in southern Chinese Han population / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association of filaggrin gene (FLG) polymorphism with atopic dermatitis (AD) in southern Chinese Han population.</p><p><b>METHODS</b>The frequencies of the 13 known FLG gene single nucleotide polymorphism(SNPs), including 3321delA, 441delA, 1249insG, E1795X, S3296X, R501X, 2282del4, R2447X, S2889X, 7945delA, 3702delG, Q2417X, R4307X, were detected in a cohort of 50 AD patients and 100 control individuals using polymerase chain reaction (PCR) and DNA sequencing.</p><p><b>RESULTS</b>FLG 3321delA and 441delA were detected in 14 (28%) and 6 (12%) AD patients, respectively. The other 11 SNPs were not detected in the patients. None of the 13 SNPs was detected in the controls.</p><p><b>CONCLUSION</b>The results suggested that the FLG gene might be associated with atopic dermatitis susceptibility in southern Chinese Han population.</p>
