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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -16 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.58).
BP6
Variant 19-11035140-C-G is Benign according to our data. Variant chr19-11035140-C-G is described in ClinVar as Likely_benign. ClinVar VariationId is 238451.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000385 (56/1456272) while in subpopulation NFE AF = 0.0000495 (55/1110012). AF 95% confidence interval is 0.000039. There are 0 homozygotes in GnomAdExome4. There are 28 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.
