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]

Ambry Genetics

Aug 12, 2024

The c.880G>T (p.D294Y) alteration is located in exon 8 (coding exon 8) of the RIOK2 gene. This alteration results from a G to T substitution at nucleotide position 880, causing the aspartic acid (D) at amino acid position 294 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
