Genes affected

SMARCA2 (HGNC:11098): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 2) The protein encoded by this gene is a member of the SWI/SNF family of proteins and is highly 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. Alternatively spliced transcript variants encoding different isoforms have been found for this gene, which contains a trinucleotide repeat (CAG) length polymorphism. [provided by RefSeq, Jan 2014]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 17 ACMG points.

PM1

In a domain Helicase C-terminal (size 162) in uniprot entity SMCA2_HUMAN there are 25 pathogenic changes around while only 0 benign (100%) in NM_003070.5

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the SMARCA2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 93 curated pathogenic missense variants (we use a threshold of 10). The gene has 88 curated benign missense variants. Gene score misZ: 5.054 (above the threshold of 3.09). Trascript score misZ: 4.663 (above the threshold of 3.09). GenCC associations: The gene is linked to intellectual disability-sparse hair-brachydactyly syndrome, Coffin-Siris syndrome 1.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.989

PP5

Variant 9-2115850-G-A is Pathogenic according to our data. Variant chr9-2115850-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 30014.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr9-2115850-G-A is described in Lovd as [Pathogenic].
