肠病性肢皮炎是一种常染色体隐性遗传病。此病的特征表现为严重的锌缺乏。人乳的锌含量一般较之牛奶为低,但本病却见之于断奶后的婴儿。服锌制剂对本病不起作用,因此体内对锌的吸收必定有某种缺陷。 Enteropathic limb dermatitis is an autosomal recessive disease. The disease is characterized by severe zinc deficiency. The zinc content of human milk is generally lower than milk, but the disease is seen in post-weaning infants. Zinc preparations take no effect on the disease, so the body’s absorption of zinc must have some defects.
