RCV000474107 | SCV000546446 | pathogenic | Hypertrophic cardiomyopathy | 2024-11-24 | criteria provided, single submitter | clinical testing | This sequence change falls in intron 26 of the MYBPC3 gene. It does not directly change the encoded amino acid sequence of the MYBPC3 protein. It affects a nucleotide within the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individuals with hypertrophic cardiomyopathy (PMID: 30297972, 33190526; internal data). ClinVar contains an entry for this variant (Variation ID: 92690). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. |
Ambry Genetics | RCV000618232 | SCV000737355 | likely pathogenic | Cardiovascular phenotype | 2025-01-06 | criteria provided, single submitter | clinical testing | The c.2737+5G>A intronic variant results from a G to A substitution 5 nucleotides after coding exon 26 in the MYBPC3 gene. This alteration has been reported in multiple unrelated probands with hypertrophic cardiomyopathy (HCM) (Ho CY et al. Circulation, 2018 Oct;138:1387-1398; O'Hare BJ et al. Circ Genom Precis Med, 2020 Dec;13:e003013; GeneDx pers. comm.; Invitae pers. comm.; Ambry internal data). This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the majority of available evidence to date, this variant is likely to be pathogenic. |

RCV001184227 | SCV001350167 | likely pathogenic | Cardiomyopathy | 2023-03-14 | criteria provided, single submitter | clinical testing | This variant causes a G to A nucleotide substitution at the +5 position of intron 26 of the MYBPC3 gene. Splice site prediction tools predict that this variant may have a significant impact on RNA splicing. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with hypertrophic cardiomyopathy (PMID: 30297972, 32841044, 33190526; communication with external laboratories [ClinVar variation ID: 92690]). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Likely Pathogenic. |
