rs73185306 C/T is not a predisposing risk factor for inherited chromosomally-integrated human herpesvirus 6A/B

Approximately 1% of people worldwide carry a copy of the human herpesvirus 6A or 6B (HHV-6A/B) in every cell of their body. This condition is referred to as inherited chromosomally integrated HHV-6A/B (iciHHV-6A/B). The mechanisms leading to iciHHV-6A/B chromosomal integration are yet to be identified. A recent report suggested that the rs73185306 C/T single-nucleotide polymorphism (SNP) represents a favorable predisposing factor leading to HHV-6A/B integration. After genotype analysis of an independent cohort (N = 11 967), we report no association between the rs73185306 C/T SNP and HHV-6A/B chromosomal integration (odds ratio, 0.90 [95% confidence interval, .54-1.51]; P = .69).
