Is Microtia Heredity?

Posted on Tue, 17 Dec 2013

Question: I have microtia..means my one ear is smaller than the other..but hearing ok. My pregnant daughter's ears are totally normal and she has no defects. But, is there a chance that her baby might have microtia..is this hereditary ? No one else in my family have it..

Brief Answer: relax. wait and watch. Detailed Answer: Solitary ear anomalies are more of spontaneus genetic errors than as hereditary or transmissible defects. so relax. You may confirm to some extent by sonography of fetus during pregnancy.. but having known it in advance as the only problem is not going to give it any therapy. so its better to wait and watch as there is high chance that it will not recur in family unless as an accident. there may be a chance if you get your genetic map karyotype done and find it abnormal.
