SCARF2 gene is mapped to 22q11.2 region, consists of 11 exons and encodes the SCARF2. The function of SCARF2 has not been fully elucidated. It is reported that this protein belongs to the cell surface scavenger receptors family involved in lipid scavenging and other biologic processes, including pathogen clearance, endocytosis, adhesion and antigen presentation. It is further involved in the pathophysiology of several disorders, such as pathogen infections, atherosclerosis, metabolic disorders, neurodegeneration and cancer (Ishii et al., 2002; PrabhuDas et al., 2014; Zani et al., 2015).","PeriodicalId":50682,"journal":{"name":"Clinical Dysmorphology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10223416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report six subjects with MTHFR deficiency who presented with variable neurological phenotypes which could be viewed as a continuous spectrum. Fatal infantile encephalopathy was observed in one family, whereas another patient presented at 27 years with acute leukoencephalopathy and recovered within 3 months. Intermediate forms presenting as complicated hereditary spastic paraparesis of variable severity were observed in four subjects. Clinical and molecular information of the 207 cases reported in literature were also retrieved and analyzed. We categorized all subjects into three categories - severe, intermediate and mild forms according to the clinical presentation. In addition, a total of 286 disease-causing variations reported to date were analyzed. These included seven disease-causing variants reported in this study of which one is novel. Some genotype-phenotype correlation could be seen which corroborated with previous observations. However, inter- and intrafamilial variability was also noted.
