Genes affected

RPS6KB2 (HGNC:10437): (ribosomal protein S6 kinase B2) This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains a kinase catalytic domain and phosphorylates the S6 ribosomal protein and eukaryotic translation initiation factor 4B (eIF4B). Phosphorylation of S6 leads to an increase in protein synthesis and cell proliferation. [provided by RefSeq, Jan 2015]

The c.397G>A (p.E133K) alteration is located in exon 5 (coding exon 5) of the RPS6KB2 gene. This alteration results from a G to A substitution at nucleotide position 397, causing the glutamic acid (E) at amino acid position 133 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
