Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP2PP3_Moderate
The NM_001018005.2(TPM1):c.625G>T(p.Ala209Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,842 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. A209T) has been classified as Likely pathogenic.

Hypertrophic cardiomyopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 19, 2022 | This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 209 of the TPM1 protein (p.Ala209Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TPM1-related conditions. ClinVar contains an entry for this variant (Variation ID: 567036). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
