Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 1P and 2B. PP2BP4_Moderate
The NM_001267550.2(TTN):c.74224C>T(p.Arg24742Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000155 in 1,613,128 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/19 in silico tools predict 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. R24742H) has been classified as Uncertain significance.
