Genes affected

RPS6KA3 (HGNC:10432): (ribosomal protein S6 kinase A3) 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 members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Mutations in this gene have been associated with Coffin-Lowry syndrome (CLS).

Variant summary: RPS6KA3 c.2168G>A (p.Arg723His) results in a non-conservative amino acid change located in the Ribosomal protein S6 kinase alpha-3, C-terminal catalytic domain (IPR041905) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0016 in 203701 control chromosomes, predominantly at a frequency of 0.0099 within the Finnish subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within Finnish control individuals in the gnomAD database is approximately 2 fold of the estimated maximal expected allele frequency for a pathogenic variant in RPS6KA3 causing Coffin-Lowry Syndrome phenotype (0.005), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Finnish origin. To our knowledge, no experimental evidence demonstrating its impact on protein function have been reported. Eight ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance (n=2), likely benign (n=2) and benign (n=4). Based on the evidence outlined above, the variant was classified as benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
