Genes affected

HIPK1 (HGNC:19006): (homeodomain interacting protein kinase 1) The protein encoded by this gene belongs to the Ser/Thr family of protein kinases and HIPK subfamily. It phosphorylates homeodomain transcription factors and may also function as a co-repressor for homeodomain transcription factors. Alternative splicing results in four transcript variants encoding four distinct isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3995807).

The c.848A>G (p.K283R) alteration is located in exon 2 (coding exon 1) of the HIPK1 gene. This alteration results from a A to G substitution at nucleotide position 848, causing the lysine (K) at amino acid position 283 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
