Patient's question:
I lost my right hand in an accident, and I gave birth to a male baby. He is two weeks old and has both hands missing. Sometimes, when he is hungry, he will stick out his tongue to lick. During pregnancy, the screening for Down syndrome showed high risk, but the follow-up non-invasive DNA test showed low risk. Could he be a Down syndrome child?Doctor's answer:
The condition of palm lines can reappear and be passed down to the next generation through generational inheritance. If both hands of the child have interrupted palm lines, it cannot be used to confirm Down syndrome. Interrupted palm lines are more common in certain congenital diseases. The re-examination of DNA during pregnancy showed a low-risk result, indicating that there should be no major issues. Because if the baby is hungry and wants to eat, it will also exhibit such reactions. The reappearance of lifting the tongue to lick is a normal feeding reflex.
