Genes affected

UTP23 (HGNC:28224): (UTP23 small subunit processome component) Enables mRNA 3'-UTR binding activity and mRNA 5'-UTR binding activity. Predicted to be involved in rRNA processing. Predicted to act upstream of or within endonucleolytic cleavage in 5'-ETS of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be part of small-subunit processome. Predicted to be active in nucleolus. Implicated in colorectal adenocarcinoma. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method:clinical testing

The c.538G>C (p.E180Q) alteration is located in exon 3 (coding exon 3) of the UTP23 gene. This alteration results from a G to C substitution at nucleotide position 538, causing the glutamic acid (E) at amino acid position 180 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
