Studies of collagen gene polymorphisms associated with predisposition to early recurrent miscarriages revealed significant differences in the distribution of COL1A1 C-1997A C>A (rs1107946) genotypes and alleles in the group of pregnant patients with early miscarriages in comparison with controls (normal pregnancy). Identification of COL1A1 C-1997A C>A (rs1107946) collagen gene polymorphisms at the stage of pregnancy planning will make it possible to form early miscarriage risk groups for more thorough preparation to gestation and optimization of follow up of this patient population.
