Genes affected

ARID2 (HGNC:18037): (AT-rich interaction domain 2) This gene encodes a member of the AT-rich interactive domain (ARID)-containing family of DNA-binding proteins. Members of the ARID family have roles in embryonic patterning, cell lineage gene regulation, cell cycle control, transcriptional regulation and chromatin structure modification. This protein functions as a subunit of the polybromo- and BRG1-associated factor or PBAF (SWI/SNF-B) chromatin remodeling complex which facilitates ligand-dependent transcriptional activation by nuclear receptors. Mutations in this gene are associated with hepatocellular carcinomas. A pseudogene of this gene is found on chromosome1. [provided by RefSeq, Dec 2016]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 12-45730106-CCA-C is Pathogenic according to our data. Variant chr12-45730106-CCA-C is described in ClinVar as [Pathogenic]. Clinvar id is 1177333.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr12-45730106-CCA-C is described in Lovd as [Pathogenic].
