新生兒溶血症(HDN, Hemolytic disease of the fetus and newborn)是一種第二型過敏反應,是由於母親和胎兒的血型不同而引起的疾病。若母親體內有對抗胎兒血型的抗體,這些抗體便會經過胎盤,進入胎兒體內,攻擊胎兒的紅血球,引起溶血反應,导致婴儿出现貧血、網狀血球增多或黃疸等症状。嚴重的可能致死。

異常型

cis-AB

極少數人類個體的一條染色體中同時存在一個cis-AB基因,它編碼的酶可以同時催化A抗原和B抗原的合成。cis-AB是從一個親本遺傳而來的,因此即便其基因型是cisAB / O,也會表現為AB型,若與O型血的人(基因型O / O)生育,子女的血型可能是AB或O,而不像通常AB型血與O型血的父母只能有A或B型血的子女。
