Overview
Syndromic frontonasal dysplasia refers to a group of rare birth defects that affect the development of the face, particularly the middle part of the face including the nose, forehead, and the area between the eyes. The term 'OBSOLETE' in the official name means that this category has been retired and reclassified into more specific subtypes in medical databases. Patients previously grouped under this label are now categorized into more precise diagnoses such as frontonasal dysplasia with alopecia and genital anomalies (ALX homeobox gene-related), acromelic frontonasal dysplasia, or other specific syndromic forms. In these conditions, the face does not form properly during early pregnancy. Common features include a wide space between the eyes (hypertelorism), a broad or split nose, a cleft in the middle of the upper lip, and sometimes a gap in the front part of the skull. Because these are 'syndromic' forms, other body systems may also be affected, including the brain, limbs, eyes, or genitals, depending on the specific subtype. Treatment is mainly supportive and surgical. Reconstructive surgery can help correct facial differences, and other specialists may be needed depending on which body systems are involved. Genetic testing is important to determine the exact subtype, which helps guide treatment and predict what other health issues may arise. Early diagnosis allows families to plan appropriate care and connect with the right medical team.
