Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 1P and 1B. PP2BP4
The NM_001267550.2(TTN):āc.79636A>Gā(p.Thr26546Ala) variant causes a missense change. The variant allele was found at a frequency of 0.0000545 in 1,613,400 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ā ). Synonymous variant affecting the same amino acid position (i.e. T26546T) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Apr 08, 2021 | Variant summary: TTN c.71932A>G (p.Thr23978Ala) results in a non-conservative amino acid change located in the A-band region of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.4e-05 in 248370 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.71932A>G has been reported in the literature in at-least one individual affected with Dilated Cardiomyopathy (example, Mazzarotto_2020). These report(s) do not provide unequivocal conclusions about association of the variant with Dilated Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. - |
