Invitae | RCV000799412 | SCV000939073 | pathogenic | Myofibrillar myopathy 6; Dilated cardiomyopathy 1HH | 2019-06-10 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon 4 of the BAG3 gene. The 5' boundary is likely confined to intron 3. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. A similar deletion of exon 4 has been observed to segregate with dilated cardiomyopathy in a family (PMID: 21353195). This variant disrupts the p.Glu455 amino acid residue in BAG3. Other variant(s) that disrupt this residue have been observed in affected individuals (PMID: 21459883, 25008357), suggesting that it is a clinically significant residue. As a result, variants that disrupt this residue are likely to be causative of disease. For these reasons, this variant has been classified as Pathogenic. |
