Holt–Oram syndrome (HOS) (OMIM 142900) is characterized by upper‐extremity malformations involving the radial, thenar, or carpal bones and a personal and/or family history of congenital heart defects (CHDs). It is inherited in an autosomal dominant manner. The TBX5 gene located on chromosome 12 (12q24.1) is the only gene currently known to be associated with HOS and is associated with variable phenotypes. We report on the clinical and molecular characterization of a HOS family with three affected individuals and a novel mutation (Lys88ter). We discuss genotype–phenotype correlations, the presence of foot anomalies in one affected individual, and the role of atypical features in HOS differential diagnosis. © 2008 Wiley‐Liss, Inc.
