Contribution of miR-124 rs531564 polymorphism to the occurrence of congenital Zika syndrome.

ABSTRACT: Zika virus (ZIKV) cause Congenital Zika Syndrome (CZS) in individuals exposed during pregnancy. Studies have shown that ZIKV infection positively regulates the miR-124 expression in neural cells, which leads to a decrease of TFRC, a gene targeted of this miRNA. Both miR-124 and TFRC exhibit a pivotal role in nervous system development. Therefore, in this study we aimed to investigate whether genetic variants that affect the expression of these genes could act together with ZIKV to increase the risk of individuals developing CZS. TFRC rs406271 and MIR-124-1 rs531564 polymorphisms were genotyped, using TaqMan® Genotyping Assays, in a sample of children who were exposed to ZIKV during pregnancy, of whom 40 were born with CZS and 48 without congenital anomalies. We identified that individuals
