Genes affected
RIOK3 (HGNC:11451): (RIO kinase 3) This gene was first identified by the similarity of its product to the Aspergillus nidulans SUDD protein. This gene is now recognized as a member of the right open reading frame (RIO) kinase gene family. This gene encodes a serine/threonine kinase that localizes to the cytoplasm and plays a role in the processing of the pre-40 S ribosomal subunit. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.1154C>T (p.A385V) alteration is located in exon 9 (coding exon 9) of the RIOK3 gene. This alteration results from a C to T substitution at nucleotide position 1154, causing the alanine (A) at amino acid position 385 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
