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]

The c.31T>A (p.S11T) alteration is located in exon 2 (coding exon 1) of the TBX22 gene. This alteration results from a T to A substitution at nucleotide position 31, causing the serine (S) at amino acid position 11 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
