Most children with inborn errors of metabolism are born healthy without malformations as the fetus is protected by the metabolic activity of the placenta. However, certain inborn errors of the fetus have teratogenic effects although the mechanisms responsible for the malformations are not generally understood. Inborn errors in the mother may also be teratogenic. The adverse effects of these may be reduced by improved metabolic control of the biochemical disorder.
大多数患有先天性代谢缺陷的儿童出生时是健康的,没有畸形,因为胎儿受到胎盘代谢活动的保护。然而,某些胎儿先天性代谢缺陷具有致畸作用,尽管导致畸形的机制通常尚不清楚。母亲的先天性代谢缺陷也可能具有致畸性。改善对生化紊乱的代谢控制可能会减少这些不良影响。
