Down syndrome associated with clinical manifestations of Kabuki syndrome: report of a case

OBJECTIVE: To describe an atypical case of Down syndrome presenting with additional clinical manifestations that might be components of Kabuki (Niikawa-Kuroki) syndrome.CLINICAL REPORT: We report the clinical history of a 19-month-old girl with a 47,XX, +21 karyotype, who presented brachycephaly, flat face, long palpebral fissures, eversion of the lateral portion of the lower eyelids, arched eyebrows with sparse lateral regions, long eyelashes, epicanthus, cortical cataract, small ears, protruding tongue, muscular hypotonia, developmental delay, hyperflexibility of joints, brachydactyly, and dermatoglyphic abnormalities.CONCLUSION: The diagnosis of Down syndrome was confirmed cytogenetically. However, the presence of additional anomalies - mainly in the ocular region - suggested that the child might also have the Kabuki syndrome.
