Introduction:
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, 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
PCR-RFLP method.
Results:
On the genotype level, three analysis models were applied namely co-dominant, dominant and
recessive genotypes. GSDMB CC genotype was found to be significant protective effect against
of 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
