Genes affected
RRN3 (HGNC:30346): (RRN3 homolog, RNA polymerase I transcription factor) Enables RNA polymerase I core promoter sequence-specific DNA binding activity. Predicted to be involved in transcription initiation from RNA polymerase I promoter. Predicted to act upstream of or within several processes, including DNA-templated transcription, initiation; negative regulation of intrinsic apoptotic signaling pathway by p53 class mediator; and regulation of transcription, DNA-templated. Located in nucleolus. [provided by Alliance of Genome Resources, Apr 2022]
PDXDC1 (HGNC:28995): (pyridoxal dependent decarboxylase domain containing 1) Enables cadherin binding activity. Predicted to be involved in carboxylic acid metabolic process. Located in Golgi apparatus. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.1634G>T (p.G545V) alteration is located in exon 16 (coding exon 16) of the RRN3 gene. This alteration results from a G to T substitution at nucleotide position 1634, causing the glycine (G) at amino acid position 545 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
