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]

The c.1371A>C (p.E457D) alteration is located in exon 12 (coding exon 12) of the RIOK3 gene. This alteration results from a A to C substitution at nucleotide position 1371, causing the glutamic acid (E) at amino acid position 457 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
