For patients with dental defects, advise early dental evaluation and intervention and encourage routine dental hygiene. Before birth, these disorders result in the abnormal development of structures including the skin, hair, nails, teeth, and sweat glands. Most cases are caused by mutations in the EDA gene, which are inherited in an X-linked recessive pattern. Antley-Bixler syndrome is inherited in an autosomal recessive pattern, which means the defective gene is located on an autosome, and two copies of the gene (one inherited from each parent) are required to be born with the disorder.
