[20] in 2021, which included 179 female pregnant patients with inherited thrombophilia, analyzed neonatal outcomes and concluded that FGR was statistically significantly associated with the homozygous mutation of factor V Leiden and combined MTHFR and factor V Leiden mutations (Table 1). Here, F5 is linked to Rare hereditary thrombophilia.
