MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit preweaning lethality associated with reduced cell proliferation and embryonic growth retardation. [provided by MGI curators]
