Introduction A COVID-19 disease, caused by the SARS-CoV-2, created signi cant concern since December 2019 worldwide. The virus is known to be highly transmissible. Heterogenic clinical features even vary more among SARS-CoV-2 variants from asymptomatic forms to severe symptoms. Previous studies revealed an association between COVID-19 and vitamin D de ciency resulting from its low levels in COVID-19 patients. To our knowledge, there is no scienti c investigation that evaluates the direct association between SARS-CoV-2 variants of concern and VDR gene markers in Cyprus. Thus, the present study aimed to identify the putative impact of VDR gene polymorphisms on SARS-CoV-2 infection among different variants. Methods The nasopharyngeal swabs were taken from a total number of 600 patients who were admitted to Near East University Hospital COVID-19 PCR Diagnosis Laboratory for routine SARS-CoV-2 RT-qPCR test. The RT-qPCR negative resulting samples were taken as control samples (n = 300). On the other hand, the case group consisted of patients who were SARS-CoV-2 RT-qPCR positive, infected with either SARS-CoV-2 Alpha (n = 100), Delta (n = 100), or Omicron (n = 100) variants. Two VDR gene polymorphisms, TaqI-rs731236 T > C and FokI-rs10735810 C > T, were genotyped by PCR-RFLP. Results The mean age of the COVID-19 patient's ± SD was 46.12 ± 12.36 and 45.25 ± 12.71 years old for the control group (p > 0.05). The gender distribution of the patient group was 48.3% female and 51.7% male and for the control group 43% female and 57% male (p > 0.05). Signi cant differences were observed in genotype frequencies of FokI and TaqI variants between SARS-CoV-2 patients compared to the control group (p < 0.005). Furthermore, the risk alleles, FokI T allele and TaqI C, were found to be statistically signi cant (OR = 1.80, 95% CI = 1.42-2.29, OR = 1.62, 95% CI = 1.27-2.05, respectively) in COVID-19 patients. The highest number of patients with wild-type genotype was found in the control group, which is 52.9% compared with 17.5% in the case group. Moreover, most of the COVID-19 patients had heterozygous/homozygous genotypes, reaching 82.5%, while 47.1% of the control group patients had heterozygous/homozygous genotypes. Conclusion Our results suggested that patients with FokI and TaqI polymorphisms might tend to be more susceptible to getting infected with the SARS-CoV-2. Overall, ndings from this study provided evidence regarding vitamin D supplements recommendation in individuals with vitamin D de ciency/insu ciency in the perior post-COVID-19 pandemic.
