Genes affected

RPS6KB1 (HGNC:10436): (ribosomal protein S6 kinase B1) This gene encodes a member of the ribosomal S6 kinase family of serine/threonine kinases. The encoded protein responds to mTOR (mammalian target of rapamycin) signaling to promote protein synthesis, cell growth, and cell proliferation. Activity of this gene has been associated with human cancer. Alternatively spliced transcript variants have been observed. The use of alternative translation start sites results in isoforms with longer or shorter N-termini which may differ in their subcellular localizations. There are two pseudogenes for this gene on chromosome 17. [provided by RefSeq, Jan 2013]

The c.740G>A (p.G247E) alteration is located in exon 8 (coding exon 8) of the RPS6KB1 gene. This alteration results from a G to A substitution at nucleotide position 740, causing the glycine (G) at amino acid position 247 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
