Variant 7-35202453-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2

The NM_001077653.2(TBX20):c.1321G>A(p.Ala441Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000414 in 1,593,002 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A441P) has been classified as Uncertain significance.

Genes affected

TBX20 (HGNC:11598): (T-box transcription factor 20) This gene encodes a T-box family member. The T-box family members share a common DNA binding domain, termed the T-box, and they are transcription factors involved in the regulation of developmental processes. This gene is essential for heart development. Mutations in this gene are associated with diverse cardiac pathologies, including defects in septation, valvulogenesis and cardiomyopathy. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]
