Gene profiling on mandibular arches (MdPA1) from Tbx1+/+ and Tbx1-/- mouse embryos

Velo-cardio-facial syndrome/DiGeorge syndrome/22q11.2 deletion syndrome (22q11DS) patients have a submucous cleft palate, velo-pharyngeal insufficiency associated with hypernasal speech, facial muscle hypotonia and feeding difficulties. Inactivation of both alleles of mouse Tbx1, encoding a T-box transcription factor, deleted on 22q11.2, results in a cleft palate and a reduction or loss of branchiomeric muscles. To identify genes downstream of Tbx1 for myogenesis, gene profiling was performed on mandibular arches (MdPA1) from Tbx1+/+ and Tbx1-/- mouse embryos.
