Summary: 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]

5 putative missense mutations were identified, 3 located in T-box binding domain (R120Q, R126W, and R151L) that affects DNA binding and/or transcriptional repression. 2 novel C-terminal mutations, P389Q and S400Y, did not affect TBX22 activity.
Title: Cleft lip with cleft palate, ankyloglossia, and hypodontia are associated with TBX22 mutations.
Analysis of the TBX22 promoter region revealed seven sequence variants, two of which are associated with cleft palate; this effect is stronger in a subgroup stratified for the presence of ankyloglossia.

TBX22 mutations are responsible for a significant proportion of Thai non-syndromic cleft palate cases.
Title: TBX22 mutations are a frequent cause of non-syndromic cleft palate in the Thai population.
TBX22 is a target for the small ubiquitin-like modifier SUMO-1 and this modification is required for TBX22 repressor activity.
Title: TBX22 missense mutations found in patients with X-linked cleft palate affect DNA binding, sumoylation, and transcriptional repression.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
