Genes affected

RIOK1 (HGNC:18656): (RIO kinase 1) The protein encoded by this gene competes with pICln for inclusion in the protein arginine methyltransferase 5 complex. This complex targets substrates for dimethylation. The encoded protein is essential for the last steps in the maturation of 40S subunits. [provided by RefSeq, Jan 2017]

Ambry Genetics

Oct 25, 2022

The c.449A>G (p.K150R) alteration is located in exon 5 (coding exon 5) of the RIOK1 gene. This alteration results from a A to G substitution at nucleotide position 449, causing the lysine (K) at amino acid position 150 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
