Variant (CDS) | Variant (protein) | Variant Type | Variant Effect | Genomic Location (GRCh37) | ExAC Frequency |
c.100096G>A | p.V33366I (Val > Ile) | substitution | missense | chr2:179401740 (reverse strand) | 0.02881643 |
As this variant is present at a population frequency of 0.02881643 (ExAC mean allelic frequency), it is highly unlikely to be pathogenic.
The role on non-truncating TTN variants in cardiac disease has not yet been analysed in these studies.

The Exome Aggregation Consortium (ExAC) is a database of 60,706 unrelated individuals sequenced as part of various disease-specific and population genetic studies. There is partial overlap between ExAC and 1000 Genomes (1KG) (1,851 of the 2,504 samples in 1KG) and the Exome Sequencing Project (ESP) (3,936 of the 6,500 samples in ESP).
