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 GeneticsOct 27, 2021The c.1517T>G (p.L506R) alteration is located in exon 15 (coding exon 15) of the RRN3 gene. This alteration results from a T to G substitution at nucleotide position 1517, causing the leucine (L) at amino acid position 506 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
