Preaxial polydactyly in neurofibromatosis 1Shinawi, Marwana b; Patel, Millan S.a bClinical Dysmorphology: July 2007 - Volume 16 - Issue 3 - p 193-194 doi: 10.1097/MCD.0b013e3280e1cc54 SHORT CASE REPORT Buy Abstract Author InformationAuthors Article MetricsMetrics Although skeletal manifestations are a cardinal feature of neurofibromatosis 1, they are largely confined to the axial skeleton and tibiae. In contrast, congenital malformations of the extremities are less common in patients with neurofibromatosis 1, occurring in fewer than 10%. We describe a boy with bilateral, symmetrical polysyndactyly (preaxial polydactyly type IV) and neurofibromatosis 1. This report discusses peripheral skeletal malformations in neurofibromatosis 1 and their possible etiology. aDepartment of Molecular and Human Genetics, Baylor College of Medicine bTexas Children's Hospital, Houston, Texas, USA Correspondence to Millan S.
