KCNH2 and Fanconi anemia complementation group F: Furthermore, the genes (i.e., KCNA5, KCND3, and KCNH2) coding the α-subunit of the voltage-gated potassium channels Kv1.5, Kv4.3, and Kv11.1, and the α-subunit of the inwardly rectifying potassium channels Kir2.1, Kir3.4, and Kir6.1 (i.e., KCNJ2, KCNJ5, and KCNJ8) also showed significant associations with fAF risk.
