Genes affected
RNASEH2B (HGNC:25671): (ribonuclease H2 subunit B) RNase H2 is composed of a single catalytic subunit (A) and two non-catalytic subunits (B and C) and specifically degrades the RNA of RNA:DNA hybrids. The protein encoded by this gene is the non-catalytic B subunit of RNase H2, which is thought to play a role in DNA replication. Multiple transcript variants encoding different isoforms have been found for this gene. Defects in this gene are a cause of Aicardi-Goutieres syndrome type 2 (AGS2). [provided by RefSeq, Nov 2008]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 11, 2023This sequence change creates a premature translational stop signal (p.Ser240*) in the RNASEH2B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RNASEH2B are known to be pathogenic (PMID: 17846997). This variant is present in population databases (rs372632599, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with RNASEH2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 582587). For these reasons, this variant has been classified as Pathogenic. -
