Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_017970.4(NRDE2):​c.3278G>T​(p.Arg1093Met) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1093K) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: NRDE2 NM_017970.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.26

Genes affected

NRDE2 (HGNC:20186): (NRDE-2, necessary for RNA interference, domain containing) Involved in several processes, including RNA splicing; negative regulation of RNA catabolic process; and positive regulation of RNA export from nucleus. Located in nuclear speck and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]
