Abstract
Aicardi-Goutières syndrome (AGS) is an autosomal recessive disease that mimics congenital viral infection and mainly affects the brain, immune system, and skin. The dominant clinical symptom is the subacute onset of severe encephalopathy, which manifests as irritability, loss of ability, slowing of head growth, and poor nutrition. Arteriopathy in AGS is an uncommon manifestation usually associated with mutations in the SAMHD1 gene. We present a rare case of a 3-year-old male due to failure to thrive, global developmental delay, microcephaly, poor vision, upper and lower limbs spasticity, and gastroesophageal reflux disease (GERD), who harbored early stenotic lesions of the large and medium intracranial arteries with ischemic sequelae in the early postnatal life. Performed genetic testing confirmed homozygous gene mutation, SAMHD1 associated with AGS type 5. By reviewing the available literature, we were able to find only one patient whose arterial lesions were diagnosed after 6 months.

BIOMED RESEARCH INTERNATIONAL 2015; 2015:739586. [PMID: 26504826 PMCID: PMC4609382 DOI: 10.1155/2015/739586] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2015] [Revised: 09/11/2015] [Accepted: 09/15/2015] [Indexed: 11/17/2022]
Abstract
BACKGROUND To investigate whether one or more SAMHD1 gene mutations are associated with cerebrovascular disease in the general population using a Chinese stroke cohort. METHODS Patients with a Chinese Han background (N = 300) diagnosed with either cerebral large-artery atherosclerosis (LAA, n = 100), cerebral small vessel disease (SVD, n = 100), or other stroke-free neurological disorders (control, n = 100) were recruited. Genomic DNA from the whole blood of each patient was isolated, and direct sequencing of the SAMHD1 gene was performed. Both wild type and mutant SAMHD1 proteins identified from the patients were expressed in E. coli and purified; then their dNTPase activities and ability to form stable tetramers were analysed in vitro. RESULTS Three heterozygous mutations, including two missense mutations c.64C>T (P22S) and c.841G>A (p.E281K) and one splice site mutation c.696+2T>A, were identified in the LAA group with a prevalence of 3%. No mutations were found in the patients with SVD or the controls (p = 0.05). The mutant SAMHD1 proteins were functionally impaired in terms of their catalytic activity as a dNTPase and ability to assemble stable tetramers. CONCLUSIONS Heterozygous SAMHD1 gene mutations might cause genetic predispositions that interact with other risk factors, resulting in increased vulnerability to stroke.
