Bird-face syndrome can be inherited. Bird-face syndrome, also known as maxillofacial hypoplasia and deafness syndrome, belongs to a kind of congenital hereditary disease, it is a hereditary disease, some patients do not have a clear family genetic history, it may be caused by gene mutation. Bird-face syndrome is caused by an autosomal dominant gene mutation, which results in deformities of the head and face, and can be characterized by a bird-like face, i.e., small eyes, a hawkish nose, and usually accompanied by hypoplasia of the jawbone, which is only a lump in the ear, and drooping of the upper eyelid, which makes it impossible for the eye to open normally. After a period of growth and development, this condition results in the appearance of a distinctive bird face. The outward appearance varies from patient to patient, i.e., the faces of parents and children with bird-face syndrome are not identical, but may differ slightly. The autosomal dominant gene may be picked up by the next generation of a person with bird-face syndrome, and a genetic mutation can also cause the condition. Children with abnormal facial development are advised to consult a specialist as soon as possible.
