Genes affected

TBX6 (HGNC:11605): (T-box transcription factor 6) 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. Knockout studies in mice indicate that this gene is important for specification of paraxial mesoderm structures. [provided by RefSeq, Aug 2008]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BP6: Variant 16-30091070-G-A is Benign according to our data. Variant chr16-30091070-G-A is described in ClinVar as Benign. ClinVar VariationId is 259447.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0227 (3456/152296) while in subpopulation NFE AF = 0.0348 (2365/67998). AF 95% confidence interval is 0.0336. There are 45 homozygotes in GnomAd4. There are 1715 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 3456 Unknown,AD,SD gene.
