Genes affected

AGO2 (HGNC:3263): (argonaute RISC catalytic component 2) This gene encodes a member of the Argonaute family of proteins which play a role in RNA interference. The encoded protein is highly basic, and contains a PAZ domain and a PIWI domain. It may interact with dicer1 and play a role in short-interfering-RNA-mediated gene silencing. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

AGO2 Gene-Disease associations (from GenCC):

• Lessel-Kreienkamp syndrome

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Illumina, Labcorp Genetics (formerly Invitae), ClinGen

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BP6: Variant 8-140551294-G-C is Benign according to our data. Variant chr8-140551294-G-C is described in ClinVar as Benign. ClinVar VariationId is 768267.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.854 is higher than 0.05.
