What Are The Chances Of Chromosome Defect Reoccurring During Future Pregnancies?
Question: Hi.. i am 30 year old lady.5 month back i got married.last month i completed 12 week pregnancy .Last week I was terminated my first baby because of baby affected with cystic hygroma with trisomy 16 chromosomes. 5.5 mm length was founded. So we will planning for next pregnancy after 6 month.now I have doubt the problem it will affect mysecond baby or not...pls help me..I am very sad.
Brief Answer:
Karyotype of parents advised
Detailed Answer:
Hi XXXX, I have gone through your question and understand your concerns. Trisomy16 is a chromosomal anomaly, and in this situation the karyotype of both yours and your husbands' s should be done to know any chromosomal aberration if present in either or both of you. This is because the chromosomal anomaly comes in fetus either spontaneously during conception or is transmitted from parents, which is minor in parent and is not noticeable, but takes a abnormal form in the fetus.
If karyotype of both of you is normal, then you can plan for next pregnancy with a very very rare chances of recurrence on fetus.
However, if karyotype is abnormal in either of you, then you should consult a fetal medicine specialist as you will be needing a amniocentesis of fetus at 16 weeks to rule out the chromosomal anomalies in the fetus.
Hope you found the answer helpful. Please do get back for further queries.
Wishing you good health.
