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]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, RPS6KB1
• BP4: Computational evidence support a benign effect (MetaRNN=0.09029004).

The c.1384T>C (p.S462P) alteration is located in exon 15 (coding exon 15) of the RPS6KB1 gene. This alteration results from a T to C substitution at nucleotide position 1384, causing the serine (S) at amino acid position 462 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
