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.238G>T (p.A80S) alteration is located in exon 2 (coding exon 2) of the RIOK1 gene. This alteration results from a G to T substitution at nucleotide position 238, causing the alanine (A) at amino acid position 80 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
