RESUMO

The GSDMB gene encodes gasdermin B from the family of gasdermin domain-containing proteins involved in various cellular processes related to tumor development and progression, such as differentiation, cell cycle control and apoptosis. Previously, we conducted GWAS on asthma in the Volga-Ural region of Russia and found SNPs associated with asthma with genome-wide significance (rs9303277, rs8067378, rs2290400, rs7216389, rs4795405) and located in the chromosomal region 17q12-q21, which contains IKZF3 (IKAROS family zinc finger 3), ZPBP2 (zona pellucida binding protein-like), GSDMB (gasdermin B), ORMDL3 (orosomucoid 1-like 3) and LRRC3C (leucine-rich repeat-containing 3C) genes. In the present study, we investigated the association of SNPs of the GSDMB gene with the development of various allergic diseases and their combined manifestations in individuals of Russian, Tatar and Bashkir ethnic origin. Our results revealed that polymorphic variants rs7216389, rs2290400 and rs2305480 are associated with the development of allergic diseases as well as with asthma and asthma combined with allergic rhinitis. We did not reveal the association of rs7216389 and rs2290400 with the development of allergic rhinitis and atopic dermatitis in the groups of patients without asthma symptoms. This may reflect a more important role of these SNPs in the development of asthma.

RESUMO

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by age-specific localization, dryness, itch and hypersensitivity to allergens. In our study, we investigated FLG gene mutations and CNVs in AD patients and control subjects of different ethnic origin from Volga-Ural region. AD group included 303 patients (177 Russians, 126 Tatars). Control group consisted of 261 healthy individuals (152 Russians, 109 Tatars). The study revealed 66 FLG mutation carriers and demonstrated an association between c.2282del4 deletion and AD development in Russians and Tatars of Volga-Ural region of Russia. In the analysis of the FLG gene CNVs, the most common was 10-repeat allele in both Russian and Tatar patients and controls. We were unable to find any significant difference in CNV repeats count between AD patients and control individuals.
