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]

Uncertain significance, criteria provided, single submitter	clinical testing	Baylor Genetics	Aug 13, 2023	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jan 27, 2024	This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 365 of the SMARCE1 protein (p.Glu365Asp). This variant is present in population databases (rs773859296, gnomAD 0.02%). 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: 407068). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SMARCE1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Dec 04, 2023

The SMARCE1 c.1095G>C variant is predicted to result in the amino acid substitution p.Glu365Asp. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.018% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-38785178-C-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Likely benign, criteria provided, single submitter

clinical testing

Ambry Genetics

Nov 28, 2022

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. -
