Atresia ani is a congenital malformation of anorectum
due to failure of urorectal fold to divide the cloaca completely or failure of perforation of fetal anal membranes that divides rectus and anus during fetal development, this condition is inherited in an autosomal recessive manner, but no candidate genes have been found unlike pigs (Albarella et al., 2017).
