Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2 PP3_Strong PP5

The NM_014285.7(EXOSC2):​c.593G>A​(p.Gly198Asp) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G198A) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: EXOSC2 NM_014285.7 missense
• Clinical Significance: Pathogenic no assertion criteria provided P:1
• Conservation: PhyloP100: 6.66

Genes affected

EXOSC2 (HGNC:17097): (exosome component 2) Predicted to enable RNA binding activity. Involved in positive regulation of cell growth. Located in cytoplasm; nucleolus; and nucleoplasm. Part of nuclear exosome (RNase complex). [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.967
• PP5: Variant 9-130702231-G-A is Pathogenic according to our data. Variant chr9-130702231-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 446203.Status of the report is no_assertion_criteria_provided, 0 stars.
