Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 1P and 5B. PP2BP4_StrongBP6
The NM_001267550.2(TTN):c.34571G>A(p.Arg11524Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000898 in 1,558,620 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R11524R) has been classified as Likely benign.

Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 27, 2017 | p.Arg10223Gln in exon 145 of TTN: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, gibbon, naked mole rat, chinchilla, cat, shrew, and manatee have a Gln at this position despite high nearby amino acid conservation. In addition, computa tional prediction tools do not suggest a high likelihood of impact to the protei n. It has also been identified in 19/20406 African chromosomes by the Genome Agg regation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs201622536). - |
