== Disease ==
[https://www.uniprot.org/uniprot/UNG_HUMAN UNG_HUMAN] Defects in UNG are a cause of immunodeficiency with hyper-IgM type 5 (HIGM5) [MIM:[https://omim.org/entry/608106 608106]. A rare immunodeficiency syndrome characterized by normal or elevated serum IgM levels with absence of IgG, IgA, and IgE. It results in a profound susceptibility to bacterial infections.<ref>PMID:12958596</ref> <ref>PMID:15967827</ref> 
== Function ==
[https://www.uniprot.org/uniprot/UNG_HUMAN UNG_HUMAN] Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine.
