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.

LOC124901460 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.062216166 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.4, offset of 16, new splice context is: acaGTgagg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP3: BayesDel_addAF computational evidence supports a deleterious effect, 0.304
• PP5: Variant 6-166413793-C-G is Pathogenic according to our data. Variant chr6-166413793-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2692109.Status of the report is criteria_provided_single_submitter, 1 stars.
