[https://www.uniprot.org/uniprot/SAMH1_HUMAN SAMH1_HUMAN] Defects in SAMHD1 are the cause of Aicardi-Goutieres syndrome type 5 (AGS5) [MIM:[https://omim.org/entry/612952 612952]. A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood.<ref>PMID:19525956</ref> <ref>PMID:20842748</ref>  Defects in SAMHD1 are the cause of chilblain lupus type 2 (CHBL2) [MIM:[https://omim.org/entry/614415 614415]. A rare cutaneous form of lupus erythematosus. Affected individuals present with painful bluish-red papular or nodular lesions of the skin in acral locations precipitated by cold and wet exposure at temperatures less than 10 degrees centigrade.<ref>PMID:21204240</ref>  

[https://www.uniprot.org/uniprot/SAMH1_HUMAN SAMH1_HUMAN] Putative nuclease involved in innate immune response by acting as a negative regulator of the cell-intrinsic antiviral response. May play a role in mediating proinflammatory responses to TNF-alpha signaling.<ref>PMID:18546154</ref> <ref>PMID:19525956</ref>
