Genes affected

RPS6KA2 (HGNC:10431): (ribosomal protein S6 kinase A2) This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains two non-identical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Alternative splice variants, encoding different isoforms, have been characterized.

The c.1351G>A (p.V451M) alteration is located in exon 15 (coding exon 15) of the RPS6KA2 gene. This alteration results from a G to A substitution at nucleotide position 1351, causing the valine (V) at amino acid position 451 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
