Genes affected

JARID2 (HGNC:6196): (jumonji and AT-rich interaction domain containing 2) This gene encodes a Jumonji- and AT-rich interaction domain (ARID)-domain-containing protein. The encoded protein is a DNA-binding protein that functions as a transcriptional repressor. This protein interacts with the Polycomb repressive complex 2 (PRC2) which plays an essential role in regulating gene expression during embryonic development. This protein facilitates the recruitment of the PRC2 complex to target genes. Alternate splicing results in multiple transcript variants. Mutations in this gene are associated with chronic myeloid malignancies. [provided by RefSeq, May 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, JARID2
• BP4: Computational evidence support a benign effect (MetaRNN=0.18989474).

The c.280G>A (p.D94N) alteration is located in exon 3 (coding exon 3) of the JARID2 gene. This alteration results from a G to A substitution at nucleotide position 280, causing the aspartic acid (D) at amino acid position 94 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
