Invitae | RCV001218625 | SCV001390513 | pathogenic | Multiple congenital exostosis | 2019-07-06 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Tyr22*) in the EXT1 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in EXT1 are known to be pathogenic (PMID: 10679937, 11391482, 19810120). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a 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 EXT1-related conditions. This variant is not present in population databases (ExAC no frequency). |
