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 Likely_benign. Variant got -4 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000108 (10/92949) while in subpopulation AFR AF= 0.000348 (9/25876). AF 95% confidence interval is 0.000181. There are 0 homozygotes in gnomad4. There are 0 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
