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 GeneticsFeb 28, 2023The c.1598G>A (p.R533H) alteration is located in exon 10 (coding exon 10) of the RIOK2 gene. This alteration results from a G to A substitution at nucleotide position 1598, causing the arginine (R) at amino acid position 533 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
