BMP4 and congenital heart disease: Similarly, our findings indicated the absence of the association of BMP2 rs1049007 (G > C) and rs235768 (T > A), and BMP4 rs17563(T > C) genotype variations with the risk of congenital heart disease (Pearson χ2 test, Asymptomatic p value (2-sided) = 0.624 rs1049007; p value = 0.742, rs235768; p value = 0.923, rs17563, degrees of Freedom (df) = 2 in all cases).
