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]

The c.445A>G (p.I149V) 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 445, causing the isoleucine (I) at amino acid position 149 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
