Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 1P and 1B. PP2BP4
The NM_001267550.2(TTN):c.93178C>T(p.Arg31060Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,613,692 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R31060H) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Apr 16, 2015 | The p.Arg28492Cys variant in TTN has not been previously reported in individuals with cardiomyopathy, but has been identified in 3/16508 South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Com putational prediction tools and conservation analysis do not provide strong supp ort for or against an impact to the protein. In summary, the clinical significan ce of the p.Arg28492Cys variant is uncertain. - |
