Genes affected

SMARCA4 (HGNC:11100): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4) The protein encoded by this gene is a member of the SWI/SNF family of proteins and is similar to the brahma protein of Drosophila. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein is part of the large ATP-dependent chromatin remodeling complex SNF/SWI, which is required for transcriptional activation of genes normally repressed by chromatin. In addition, this protein can bind BRCA1, as well as regulate the expression of the tumorigenic protein CD44. Mutations in this gene cause rhabdoid tumor predisposition syndrome type 2. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

To the best of our knowledge, the variant has not been reported in the published literature. The frequency of this variant in the general population, 0.00036 (8/22456 chromosomes in South Asian subpopulation, http://gnomad.broadinstitute.org), is higher than would generally be expected for pathogenic variants in this gene. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The SMARCA4 c.715G>A variant is predicted to result in the amino acid substitution p.Gly239Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.036% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-11097224-G-A), which is likely too common for an undocumented disease-causing variant. In ClinVar, this variant is interpreted as likely benign (https://www.ncbi.nlm.nih.gov/clinvar/variation/238514/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

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. -
