Invitae RCV000797420 SCV000936975 likely pathogenic Weaver syndrome 2018-08-24 criteria provided, single submitter clinical testing This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in an individual with clinical features of Weaver syndrome (Invitae). 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. Experimental studies have not been reported for this variant. If the canonical splice site is maintained and the duplicated sequence is translated, then this variant is expected to result in an in-frame insertion, for which experimental studies and prediction algorithms are not available. However, if the canonical splice site is not used, alternative splicing using the newly created splice site would likely have no effect on the translated protein. This sequence change duplicates 12 nucleotides across the intron 19/exon 20 boundary of the EZH2 gene, including part of the canonical splice site. It is expected to either cause an in-frame insertion at p.Arg732 (p.Arg732_Tyr733insCysCysPheArg) or to have no protein effect, due to utilization of a newly created alternate splice site.
