Genes affected

TBX22 (HGNC:11600): (T-box transcription factor 22) This gene is a member of a phylogenetically conserved family of genes that share a common DNA-binding domain, the T-box. T-box genes encode transcription factors involved in the regulation of developmental processes. Mutations in this gene have been associated with the inherited X-linked disorder, Cleft palate with ankyloglossia, and it is believed to play a major role in human palatogenesis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

TBX22 Gene-Disease associations (from GenCC):

• cleft palate with or without ankyloglossia, X-linked
