EFNA1 and colorectal carcinoma: Concerning the EFNA1 (rs12904) variant, we observed that the patient carriers of the G/G genotype showed an increased susceptibility for developing CRC (OR = 2.23; 95% CI = 1.44–3.46, p = 0.005, and this association was also evident under the dominant model of inheritance (A/G + G/G vs. A/A) (OR = 1.68; 95% CI = 1.17–2.41, p = 0.005).
