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 Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ARID2. . Gene score misZ 2.7332 (greater than the threshold 3.09). Trascript score misZ 4.4744 (greater than threshold 3.09). GenCC has associacion of gene with Coffin-Siris syndrome 6, Coffin-Siris syndrome.

The c.125G>A (p.G42E) alteration is located in exon 2 (coding exon 2) of the ARID2 gene. This alteration results from a G to A substitution at nucleotide position 125, causing the glycine (G) at amino acid position 42 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
