Genes affected

TBX18 (HGNC:11595): (T-box transcription factor 18) This genes codes for a member of an evolutionarily conserved family of transcription factors that plays a crucial role in embryonic development. The family is characterized by the presence of the DNA-binding T-box domain and is divided into five sub-families based on sequence conservation in this domain. The encoded protein belongs to the vertebrate specific Tbx1 sub-family. The protein acts as a transcriptional repressor by antagonizing transcriptional activators in the T-box family. The protein forms homo- or heterodimers with other transcription factors of the T-box family or other transcription factors. [provided by RefSeq, Nov 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000231 (337/1461824) while in subpopulation NFE AF = 0.000299 (333/1111994). AF 95% confidence interval is 0.000273. There are 0 homozygotes in GnomAdExome4. There are 181 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 15 AD,Unknown gene.
