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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.581T>C (p.V194A) alteration is located in exon 7 (coding exon 7) of the RIOK1 gene. This alteration results from a T to C substitution at nucleotide position 581, causing the valine (V) at amino acid position 194 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
