Invitae | RCV001232930 | SCV001405503 | pathogenic | Exostoses, multiple, type 2 | 2020-06-03 | criteria provided, single submitter | clinical testing | 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. For these reasons, this variant has been classified as Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in EXT2 are known to be pathogenic (PMID: 10679937, 19810120). Disruption of this splice site has been observed in individual(s) with multiple osteochondromas (PMID: 30334991, 29529714, 15586175, 11668521). This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 3 of the EXT2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. |
