Variant summary

Our verdict is The variant received 1 classification points (ACMG Germline Pathogenicity v2019). PM2BP4

The NM_002953.4(RPS6KA1):c.154G>T (p.Ala52Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a cumulative frequency of 0.0000329 (AC=5) in the gnomAD database across 152,172 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000305. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 10.00). Variant has been reported in ClinVar as Uncertain Significance (★).

Genes affected

RPS6KA1 (HGNC:10430): (ribosomal protein S6 kinase A1) This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 nonidentical 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. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 points.

PM2

Very rare in gnomAD for AR/unknown gene (popmax AF < threshold/10) — PM2; GnomAD popmax AF = 0.0000305 — very rare for unknown gene (threshold 0.001) — PM2 moderate.

BP4

Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Supporting).
