Genes affected

PLK2 (HGNC:19699): (polo like kinase 2) The protein encoded by this gene is a member of the polo family of serine/threonine protein kinases that have a role in normal cell division. This gene is most abundantly expressed in testis, spleen and fetal tissues, and its expression is inducible by serum, suggesting that it may also play an important role in cells undergoing rapid cell division. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

Ambry Genetics

Apr 20, 2023

The c.857A>G (p.K286R) alteration is located in exon 7 (coding exon 7) of the PLK2 gene. This alteration results from a A to G substitution at nucleotide position 857, causing the lysine (K) at amino acid position 286 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
