Invitae RCV001935269 SCV002174010 pathogenic Exostoses, multiple, type 2 2021-09-03 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with multiple osteochondromas (Invitae). This variant is not present in population databases (ExAC no frequency). This variant results in the deletion of part of exon 3 (c.620_626+158del) of the EXT2 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 EXT2 are known to be pathogenic (PMID: 10679937, 19810120).
