THE STUDY OF THE ASSOCIATION OF SINGLE-NUCLEOTIDE POLYMORPHISMS ARG25PRO OF THE TRANSFORMING GROWTH FACTOR Β1 GENE AND C634G OF THE VASCULAR ENDOTHELIAL GROWTH FACTOR GENE WITH THE RISK OF ATOPIC DERMATITIS IN CHILDREN

The growth factors such as transforming growth factor β (TGF-β) and vascular endothelial growth factor (VEGF) are played a particular role in the pathogenesis of atopic dermatitis. Therefore, the study of the genetic aspects of their association with risk of atopic dermatitis development in children is of great practical and scientific interest. Background. To study the association of the Arg25Pro polymorphisms of the TGF-β gene and the C634G gene of the VEGF gene with the risk of atopic dermatitis in children. Methods. Allelic variants of Arg25Pro gene TGF-β1 and S634G VEGFA gene in children with atopic dermatitis were studied with method of allelespecific polymerase chain reaction. The control group consisted of patients I and Ila of the health groups of the corresponding sex and age. Results. The results of genetic studies have shown that the occurrence frequency of genotype polymorphism Arg25Pro TGF-β1 gene in patients did not have significant differences from control group (p>0,05). Moreover, among patients who are heterozygous for the gene Arg25Pro TGF-β1, significantly more often had moderate (77,78%) and severe (33,33%) of course of the disease. It is established that the relationship between inheritance of C and Gallele polymorphism C634G VEGFA gene and the development of atopic dermatitis is also statistically significant (χ2=0,33, p=0,57). Conclusion. The study of polymorphisms of Arg25Pro gene of TGF-β and C634G gene of VEGF did not reveal a significant relationship between their inheritance and development of atopic dermatitis in children.
