Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 27, 2021 | 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with PTCH1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 10 of the PTCH1 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 PTCH1 are known to be pathogenic (PMID: 16301862, 16419085). - |
