TARP syndrome

TARP syndrome is a disorder marked by early lethality. It comprises Talipes equinovarus, atrial septal defect, Robin sequence (micrognathia, glossoptosis, and cleft palate), and persistence of the left superior vena cava. It is inherited in an X-linked recessive pattern. Expression analysis of mouse orthologue of the causative gene revealed that the gene is expressed in the parts where malformations in TARP syndrome are observed, such as in the branchial arches and in the limb/tail bud regions.
