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]

Ambry Genetics

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.919G>C (p.D307H) alteration is located in exon 8 (coding exon 7) of the DIS3L2 gene. This alteration results from a G to C substitution at nucleotide position 919, causing the aspartic acid (D) at amino acid position 307 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 307 of the DIS3L2 protein (p.Asp307His). This variant is present in population databases (rs780127954, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with DIS3L2-related conditions. This missense change has been observed to be homozygous, hemizygous or homoplasmic in an individual who did not have the expected clinical features for that genetic result (internal data). ClinVar contains an entry for this variant (Variation ID: 463133). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt DIS3L2 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
