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 made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SMARCA4. . Gene score misZ 6.8459 (greater than the threshold 3.09). Trascript score misZ 8.7957 (greater than threshold 3.09). GenCC has associacion of gene with uterine corpus sarcoma, Coffin-Siris syndrome 1, intellectual disability, autosomal dominant 16, rhabdoid tumor predisposition syndrome 2, familial rhabdoid tumor, hereditary nonpolyposis colon cancer, Coffin-Siris syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.024883807).
BP6
Variant 19-11039474-A-T is Benign according to our data. Variant chr19-11039474-A-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 220887.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=4, Uncertain_significance=1, Benign=1}.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000985 (15/152312) while in subpopulation SAS AF= 0.00145 (7/4826). AF 95% confidence interval is 0.00068. There are 0 homozygotes in gnomad4. There are 9 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
