Variant summary: The c.1234G>A (p.Val412Ile) in TBX5 gene is a missense change that involves a conserved nucleotide and 2/4 in silico tools predict deleterious outcome. The variant is located outside of any known functional domain and no functional studies confirming deleterious effect of this change have been reported at the time of evaluation. The variant is present in the control population dataset of ExAC at a frequency of 0.0009702 (117/ 120590 chrs tested), predominantly in individuals of African descent (0.01025; 105/ 120590 chrs tested, including 2 homozygotes. The observed frequency exceed the maximum expected allele frequency for a pathogenic variant of 0.0000013. The variant is present in a control population dataset of gnomAD at a frequency of 0.0009577 (265/276692 chrs), mainly in individuals of African origin: 0.009912 (238/24012 chrs, including 2 homozygotes). This data suggest that the variant of interest may be an ethnic-specific functional polymorphism. The variant has not, to our knowledge, been reported in affected individuals via published reports or cited by reputable databases/clinical laboratories. Taking together, the variant was classified as Benign.
