Familial Inheritance of Mandibular Arch Malformations Affecting Three Individuals in One Family
Abstract
ABSTRACT: Mandibular aplasia is defined as incomplete development of the mandibular process of the first brachial arch. Its prevalence is less than 1:70,000. It is usually associated with low-set ears, transposition of the viscera, congenital heart defects, and rib abnormalities, and is incompatible with life. In this case report, fetal demise at 26 weeks' gestation in a previous pregnancy revealed the phenotypic features listed. The second pregnancy described here resulted in therapeutic termination of a similar appearing fetus. Because of this recurrence and a positive family history, familial inheritance is postulated.This content is limited to qualifying members.
