Genes affected

DCUN1D3 (HGNC:28734): (defective in cullin neddylation 1 domain containing 3) Enables cullin family protein binding activity. Involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle; regulation of protein neddylation; and response to UV-C. Located in nucleus; perinuclear region of cytoplasm; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

DCUN1D3 links:

ERI2 (HGNC:30541): (ERI1 exoribonuclease family member 2) Predicted to enable 3'-5'-exoribonuclease activity. Predicted to be involved in exonucleolytic trimming to generate mature 3'-end of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA).

The c.551G>A (p.R184Q) alteration is located in exon 3 (coding exon 2) of the DCUN1D3 gene. This alteration results from a G to A substitution at nucleotide position 551, causing the arginine (R) at amino acid position 184 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
