Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6

The NM_152383.5(DIS3L2):​c.2563G>A​(p.Ala855Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000373 in 1,610,466 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A855D) has been classified as Uncertain significance.

Genes affected
DIS3L2 (HGNC:28648): (DIS3 like 3'-5' exoribonuclease 2) The protein encoded by this gene is similar in sequence to 3'/5' exonucleolytic subunits of the RNA exosome. The exosome is a large multimeric ribonucleotide complex responsible for degrading various RNA substrates. Several transcript variants, some protein-coding and some not, have been found for this gene. [provided by RefSeq, Mar 2012]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.2563G>A (p.A855T) alteration is located in exon 21 (coding exon 20) of the DIS3L2 gene. This alteration results from a G to A substitution at nucleotide position 2563, causing the alanine (A) at amino acid position 855 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
