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]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00203 (189/92959) while in subpopulation EAS AF= 0.00507 (15/2961). AF 95% confidence interval is 0.00312. There are 1 homozygotes in gnomad4. There are 42 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High Hemizygotes in GnomAd4 at 42 XL gene
