TBX22 [SEP] chromosome
palatogenesis. It has previously been mapped to the long arm of the X chromosome and it has now been demonstrated that mutations in the gene TBX22 are the cause of this syndrome. TBX22 mutations also result in non-syndromic cleft palate in some populations.
TBX22 is composed of seven exons spanning 8.7 kilobases of genomic DNA in Xq21.1. The TBX22 mRNA is 2099 base pairs long and encodes a 400-amino-acids protein containing a T-domain in its NH2-terminal region which has the unique feature of missing 20 amino-acids relative
TBX22
T-box transcription factor TBX22 is a protein that in humans is encoded by the "TBX22" gene.
TBX22 is a member of a phylogenetically conserved family of proteins 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 (tongue-tie), and it is believed to play a major role in human
