Abstract

The acrofacial dysostoses (AFD) are a clinically and causally heterogeneous group of conditions characterized by mandibulofacial dysostosis and a variety of limb anomalies. Several abnormalities affecting different internal organs and the central nervous system (CNS) have been described. Depending on the type of limb defects, two major groups have been delineated: (1) with predominantly pre‐axial anomalies, Nager type AFD, and (2) with predominantly post‐axial involvement, Genée–Wiedemann form of AFD, also known as POADS, respectively. Other forms of “true AFD” have been described as Kelly, Reynolds, Arens (also Tel Aviv form), Rodríguez (or Madrid form), Richieri–Costa, and Patterson–Stevenson–Fontaine types. However, whether they are distinct entities or represent variants of the same condition remains unclear. Rodírguez AFD was described as a new lethal form of AFD in three affected sibs with severe mandibular hypoplasia, severe predominantly pre‐axial limb deficiencies, absent fibulae and ribs, and internal organ anomalies, the most remarkable of which are arrhinencephaly and abnormal lung lobulation. We present a newborn girl with Rodríguez type of AFD, who died a few days after the birth due to respiratory failure. The phenotype and the cause of this condition are discussed. © 2005 Wiley‐Liss, Inc.
