agnathia-otocephaly complex
MONDO:0008740
Agnathia-holoprosencephaly-situs inversus syndrome is an extremely rare and fatal association syndrome, characterized by absence of the mandible, cerebral malformations with facial anomalies related to a defect in cleavage in the embryonic brain (e.g. synophthalmia, malformed and low-set ears fused in midline (otocephaly), agenesis of the olfactory bulbs, microstomia, hypoglossia/aglossia) and situs inversus partialis or totalis.

Otocephaly
Otocephaly, also known as agnathia–otocephaly complex, is a very rare and lethal cephalic disorder characterized by the absence of the mandible (agnathia), with the ears fused together just below the chin (synotia). It is caused by a disruption to the development of the first branchial arch. It occurs in 1 in every 70,000 embryos.
