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]

The SMARCE1 p.Gly360Asp variant was not identified in the literature nor was it identified in Cosmic. The variant was identified in dbSNP (ID: rs142193069), LOVd 3.0 and in ClinVar (classified as likely benign by Invitae and as a VUS by Genetics Services University of Chicago and Ambry Genetics). The variant was also identified in control databases in 408 of 282474 chromosomes (1 homozygous) at a frequency of 0.001444 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017) and was observed in the following populations: European (non-Finnish) in 328 of 128822 chromosomes (freq: 0.002546), South Asian in 35 of 30614 chromosomes (freq: 0.001143), Other in 8 of 7216 chromosomes (freq: 0.001109), Latino in 18 of 35434 chromosomes (freq: 0.000508), African in 12 of 24968 chromosomes (freq: 0.000481) and European (Finnish) in 7 of 25098 chromosomes (freq: 0.000279); it was not observed in the Ashkenazi Jewish and East Asian populations. The variant occurs outside of the splicing consensus sequence and 3 of 4 in silico or computational prediction software programs (MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. The p.Gly360 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
