Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 22, 2023 | This sequence change affects an acceptor splice site in intron 43 of the MYO7A gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in MYO7A are known to be pathogenic (PMID: 8900236, 25404053). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. Disruption of this splice site has been observed in individual(s) with Usher syndrome (PMID: 16963483). ClinVar contains an entry for this variant (Variation ID: 557287). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. - |
