The purpose of this review was to analyze the correlation between the prevalence of MTHFR C677T gene polymorphism and COVID-19 incidence and mortality worldwide. Data regarding MTHFR C677T gene mutation were obtained from the interrogation of the Genome Aggregation Database (genomAD), which is publicly available from the web"https//gnomad.broadinstitute.org." COVID-19 cases, including prevalence and mortality, were obtained from"https//www.worldometers.info/coronavirus" 27 August 2020. There is a clear trend toward the worldwide prevalence of MTHFR 677T and COVID-19 incidence and mortality. The prevalence of MTHFR 677T allele in the Latino population, and the incidence and mortality for COVID-19 was higher for this ethnic group than that reported for most other populations globally. Statistical analysis showed a relatively strong correlation between C677T and death from coronavirus. Genetic polymorphism of MTHFR C677T may modulate the incidence and severity of COVID-19 pandemic infection. Genetic polymorphism of MTHFR C677 T may modulate the incidence and severity of COVID-19 pandemic infection.Few in vivo studies have focused on the perivenous association of tubers and iron deposition in the deep gray nuclei in patients with tuberous sclerosis complex (TSC). We investigated this possible relationship in TSC patients using susceptibility weighted imaging (SWI) at 7 T. SWI with high spatial resolution and enhanced sensitivity was performed on 11 TSC patients in comparison with 15 age- and sex-matched healthy controls. The relationship between tubers and veins was evaluated. In addition, the phase images of SWI were processed to produce local field shift (LFS) maps to quantify iron deposition. The mean LFS in the deep gray nuclei was compared between the TSC patients and healthy controls usin
