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)

The c.967G>C (p.D323H) alteration is located in exon 8 (coding exon 8) of the RIOK2 gene. This alteration results from a G to C substitution at nucleotide position 967, causing the aspartic acid (D) at amino acid position 323 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
