Invitae | RCV000472959 | SCV000546220 | uncertain significance | Hypertrophic cardiomyopathy | 2021-08-27 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Arg249*) in the MYH7 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in MYH7 cause disease. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with MYH7-related conditions. 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. |

RCV003532128 | SCV004356969 | uncertain significance | Cardiomyopathy | 2023-07-06 | criteria provided, single submitter | clinical testing | This variant changes 1 nucleotide in exon 9 of the MYH7 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in an individual affected with left ventricular non-compaction (PMID: 28798025). This variant has been identified in 1/251458 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Clinical relevance of loss-of-function MYH7 truncation variants in autosomal dominant cardiovascular disorders is not clearly established. The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
