Abstract
Background
Previous research has linked dysregulation of the vitamin D pathway to skin diseases. In this study, we sought to explore the genetic variations in the vitamin D receptor (VDR) and vitamin D-binding protein (VDBP), alongside the estimation of serum vitamin D and VDBP levels in Chronic Urticaria (CU) patients.
Methods
Blood samples were obtained from all participants (n = 200) to assess serum vitamin D, VDBP, and total IgE levels using enzyme-linked immunosorbent assay (ELISA). Additionally, DNA was extracted from the blood samples for analysis of VDR (rs1544410, rs2228570) and VDBP (rs7041) polymorphisms using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP).
Results
CU patients exhibited elevated levels of total IgE (208.29 ± 151.293 vs. 125.91 ± 73.13 IU/ml) and VDBP (570.59 ± 158.74 vs. 314.408 ± 140.31 μg/ml) (p-value < 0.0001), as compared to controls. Further, such patients also showed lower vitamin D levels (14.57 ± 8.71 vs. 20.022 ± 8.9 ng/ml, p-value < 0.0001). Additionally, we observed that the ‘G’ and ‘C’ alleles of VDBP rs7041 and VDR rs2228570, respectively, might be a potential risk factor for the progression of CU.
Conclusion
This study provides valuable insights into the potential involvement of VDR and VDBP genetic variants in the pathogenesis of Chronic Urticaria (CU). While no significant associations were observed between these genetic variants and serum levels of vitamin D or VDBP, the identified genetic variations may play a role in increasing CU susceptibility within the Kashmiri population. Further research, including Mendelian randomization studies, is required to confirm any causal relationships.

期刊介绍:
Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
