Again, no significant relation was observed between educational level of the father and FA of the left anterior AF segment (F(2,31) = 2.365, p = .111), FA of the posterior AF segment (F(2,31) = .403, p = .672), FA of the IFOF (F(2,31) = .401, p = .673) and FA of the ILF (F(2,31) = 1.313, p = .284). Here, FOXK2 is linked to atrial fibrillation.
