Human endogenous retrovirus HERV-Fc1 association with multiple sclerosis susceptibility: a meta-analysis.
BackgroundHuman endogenous retroviruses (HERVs) are repetitive sequences derived from ancestral germ-line infections by exogenous retroviruses and different HERV families have been integrated in the genome.HERV-Fc1 in chromosome X has been previously associated with multiple sclerosis (MS) in Northern European populations.Additionally, HERV-Fc1 RNA
