Genes affected

RPS6KA4 (HGNC:10433): (ribosomal protein S6 kinase A4) This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 non-identical kinase catalytic domains and phosphorylates various substrates, including CREB1 and ATF1. The encoded protein can also phosphorylate histone H3 to regulate certain inflammatory genes. Several transcript variants encoding different isoforms have been found for this gene.

The c.1441C>G (p.L481V) alteration is located in exon 13 (coding exon 13) of the RPS6KA4 gene. This alteration results from a C to G substitution at nucleotide position 1441, causing the leucine (L) at amino acid position 481 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
