ABSTRACT
INTRODUCTION:
The genetic background of atopic dermatitis (AD) is complex, involves many genes and their participation varies in varied populations, and depends on the intensity and course of a disease. Changes in the nucleotide sequence of the FLG gene and a reduced number or a deficit of the functional product of processed profilaggrin can be one of risk factors for atopic dermatitis.AIM:
To determine the prevalence of R501X and 2282del4 mutations of the FLG gene in patients with AD. MATERIAL ANDMETHODS:
The studied group included 60 patients with clinically diagnosed AD, and the control group included 61 healthy volunteers. The study protocol included collection of biological material for tests, DNA isolation and evaluation of its quality and quantity, and PCR amplification of the isolated genetic material.RESULTS:
In the studied group, both changes in the nucleotide sequence of the FLG gene were detected and in the control group no tested mutations were detected. In 18 (30%) patients with AD, 22 mutations (4 heterozygous and 1 homozygous ones of R501X and 10 heterozygous and 7 homozygous ones of 2282del4) were detected.CONCLUSIONS:
A high rate of mutations of the FLG gene in patients with clinically diagnosed AD and pathologically dry skin was observed in the studied population. The 2282del4 mutation occurred more often than R501X.
