Auriculo-condylar syndrome (ACS) is characterized by typical ears malformation (so-called "question mark" ears), prominent cheeks, microstomia, and abnormality of the temporomandibular joint and condyle of the mandible. In this report we describe a new simplex case and a previously unreported family with affected individuals in three generations documenting clinical variability. Linkage study for markers located in candidate region for ACS1 (1p21.1-q23.3) was excluded in our familial case, reinforcing the hypothesis of genetic heterogeneity for this condition. A review of the literature focusing diagnostic criteria and features of ACS was performed.
