Genes affected

SMARCE1 (HGNC:11109): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily e, member 1) The protein encoded by this gene is part of the large ATP-dependent chromatin remodeling complex SWI/SNF, which is required for transcriptional activation of genes normally repressed by chromatin. The encoded protein, either alone or when in the SWI/SNF complex, can bind to 4-way junction DNA, which is thought to mimic the topology of DNA as it enters or exits the nucleosome. The protein contains a DNA-binding HMG domain, but disruption of this domain does not abolish the DNA-binding or nucleosome-displacement activities of the SWI/SNF complex. Unlike most of the SWI/SNF complex proteins, this protein has no yeast counterpart. [provided by RefSeq, Jul 2008]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Ser208Argfs*26) in the SMARCE1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SMARCE1 are known to be pathogenic (PMID: 23377182). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SMARCE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 212264). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

Collection Method:clinical testing

The SMARCE1 c.624_627del p.(Ser208ArgfsTer26) change deletes four nucleotides to cause a frameshift and the creation of a premature stop codon. This change is predicted to cause protein truncation or absence of protein due to nonsense-mediated decay. This variant has been reported in individuals with meningioma (PMID: 30421029, internal data). This variant is also absent in gnomAD v2.1.1 (https://gnomad.broadinstitute.org). In summary, this variant meets criteria to be classified as pathogenic. -
