Variant summary
Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_StrongBP6_Moderate
The NM_133379.5(TTN):c.14399G>A(p.Gly4800Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000124 in 1,612,932 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/15 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G4800W) has been classified as Likely benign.

Submissions by phenotype
not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jun 22, 2015 | p.Gly4800Glu in exon 45A of TTN: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, chimp, cat, and armadillo have a glutamic acid (Glu) at this position. It has also been identified 0.1% (12/8464) of East Asian chromosomes by the Exome A ggregation Consortium (http://exac.broadinstitute.org). - |
