Genes affected

RAMACL (HGNC:21234): (RNA guanine-7 methyltransferase activating subunit like) Predicted to enable RNA binding activity. Predicted to be involved in methylation and recruitment of mRNA capping enzyme to RNA polymerase II holoenzyme complex. Predicted to be part of mRNA cap binding activity complex and mRNA cap methyltransferase complex. [provided by Alliance of Genome Resources, Apr 2022]

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.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.99).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.805 is higher than 0.05.
