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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 11, 2023The c.527A>G (p.K176R) alteration is located in exon 3 (coding exon 3) of the UTP23 gene. This alteration results from a A to G substitution at nucleotide position 527, causing the lysine (K) at amino acid position 176 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
