Birth of a healthy boy after PGD for X-linked heterotaxy syndrome

摘要

Heterotaxy syndrome is a clinically and genetically heterogeneous rare disorder included in the group of congenital heart diseases (CHD). The word heterotaxy comes from the Greek "heteros", meaning "different"; and "taxis", meaning "arrangement". The thoracic and visceral organs (including the heart, liver, lungs, spleen, and stomach) have an abnormal placement, as they are situated randomly with respect to the left-right axis and with respect to one another [20].
