One in silico tool predicts a polymorphism outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect ESE sites. This variant was found in 1592/121410 control chromosomes (111 homozygotes), predominantly observed in the African subpopulation at a frequency of 0.1429258 (1487/10404). This frequency significantly exceeds the estimated maximal expected allele frequency of a pathogenic TBX5 variant (0.0000013), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. This variant has been reported in multiple affected individuals as a polymorphism. Some patient also carried a pathogenic variant, further supporting the benign classification of this variant. In addition, one clinical diagnostic laboratory classified this variant as benign. Taken together, this variant is classified as benign.
