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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2124T>G (p.F708L) alteration is located in exon 22 (coding exon 22) of the RPS6KA2 gene. This alteration results from a T to G substitution at nucleotide position 2124, causing the phenylalanine (F) at amino acid position 708 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
