title: A novel missense mutation in the TBX5 gene in a Saudi infant with Holt-Oram syndrome.
abstract: We report on a Saudi infant with Holt-Oram syndrome caused by a de novo missense mutation of the TBX5 gene. The mutation (Thr72Lys) is novel and has not been previously reported. The cardiac and limb defects in our patient were both severe, and the infant also had micrognathia and cleft palate. Previously reported cases of the Holt-Oram syndrome caused by missense mutations were reviewed and their phenotypes were compared with the phenotype of our patient.
