Genes affected
RIOK2 (HGNC:18999): (RIO kinase 2) Predicted to enable protein kinase activity. Involved in several processes, including positive regulation of rRNA processing; positive regulation of ribosomal small subunit export from nucleus; and regulation of mitotic metaphase/anaphase transition. Located in cytoplasm. Part of preribosome, small subunit precursor. [provided by Alliance of Genome Resources, Apr 2022]
LIX1-AS1 (HGNC:52976): (LIX1 and RIOK2 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.1584A>G (p.I528M) alteration is located in exon 10 (coding exon 10) of the RIOK2 gene. This alteration results from a A to G substitution at nucleotide position 1584, causing the isoleucine (I) at amino acid position 528 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
