Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 1P and 1B. PP2BP4
The NM_001267550.2(TTN):c.93262T>G(p.Phe31088Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000018 in 1,613,774 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 (★★). Synonymous variant affecting the same amino acid position (i.e. F31088F) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 10, 2020 | The p.F22023V variant (also known as c.66067T>G), located in coding exon 166 of the TTN gene, results from a T to G substitution at nucleotide position 66067. The phenylalanine at codon 22023 is replaced by valine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
