Abstract:
Background: Gasdermin A (GSDMA) and Gasdermin B (GSDMB) have been associated
with childhood and to a lesser extent with adult asthma in many populations. In this study, we investigate
whether there is an association between GSDMA (rs7212938, T/G) and GSDMB (rs7216389,
T/C) at locus 17q21.2 and risk of Allergic Rhinitis among Jordanians. Also, we aimed to determine if
there is an association between such polymorphisms and the IgE level.
Methods: The study included 112 rhinitis patients and 111 Healthy controls. Gasdermin A (GSDMA)
(rs7212938, T/G) and Gasdermin B (rs7216389, T/C) polymorphisms were genotyped using the PCRRFLP
method.
Results: On the genotype level, three analysis models were applied namely co-dominant, dominant and
recessive genotypes. GSDMB CC genotype was found to have a significant protective effect against
allergic Rhinitis (< 0.05). cc genotype was also significantly associated with higher IgE level among
the studied population.
Conclusion: The GSDMB CC of homozygous minor genotype showed a protective effect against Allergic
rhinitis. It also was found to be significantly associated with lower IgE level among the studied
population. No association was found between GSDMA with the risk of allergic Rhinitis.
