Genes affected

HIPK2 (HGNC:14402): (homeodomain interacting protein kinase 2) This gene encodes a conserved serine/threonine kinase that is a member of the homeodomain-interacting protein kinase family. The encoded protein interacts with homeodomain transcription factors and many other transcription factors such as p53, and can function as both a corepressor and a coactivator depending on the transcription factor and its subcellular localization. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.787

The c.770A>G (p.D257G) alteration is located in exon 2 (coding exon 2) of the HIPK2 gene. This alteration results from a A to G substitution at nucleotide position 770, causing the aspartic acid (D) at amino acid position 257 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
