3.Low-Set Ears
Two of the more common conditions linked to this are Down and Turner syndromes. Problems with a chromosome cause both. People with Down syndrome also have other physical differences and development issues. Turner syndrome can cause problems with how the head and the neck form, and issues with growth and puberty. Two rare conditions — Shprintzen-Goldberg and Jacobsen syndromes — also can cause low-set ears and development problems.
4.Missing External Ear
This can be a sign of anotia — a condition you’re born with. Doctors aren’t sure what causes it, but things in the environment and taking certain medications during pregnancy may play a part. It can happen by itself or along with another genetic condition. In most cases, doctors can form an outside ear with plastic surgery.
