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 Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.30109465).
• BS2: High AC in GnomAdExome4 at 6 AD gene.

The c.269C>G (p.S90C) alteration is located in exon 3 (coding exon 3) of the JARID2 gene. This alteration results from a C to G substitution at nucleotide position 269, causing the serine (S) at amino acid position 90 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
