Brown-Vialetto-Van Laere syndrome and Fazio-Londe syndrome: A novel mutation and in silico analyses.

Brown-Vialetto-Van Laere syndrome, a rare neurological disorder is due to SLC52A3 mutations. Here, the SLC52A3 protein and its mutations are in silico structurally and functionally analyzed among all the reported patients and a novel mutation is also reported. After clinical evaluations, SLC52A3 gene was sequenced and segregation analysis of the mutations was also checked. A comprehensive search was performed on the reported mutations of SLC52A3 gene. In silico structural and functional analyses of the mutations and interactome analyses of the protein were done using available software tools. Mutations of 37 affected individuals were identified. Thirty three mutations were determined. c.502A > C was a novel variant that it was segregated within the family. One mutation (c.639C > G) was responsible for 12% of the mutations. Segregation analysis, secondary structure, functional prediction achieved for the novel mutation showed pathogenicity of this variant. BVVL is a very rare disorder; SLC52A3 mutations are distributed among different populations and there might be one frequent mutation in this gene. BVVL should be more considered in Iran. In addition to segregation analysis, computational analyses could accelerate understanding the extent of pathogenicity of the novel variants.

Ictal Electroencephalographic Findings in Children with Migraine Headache.

OBJECTIVES: In this study, the EEG findings in children with migraine headache were assessed in Bahrami Hospital, Tehran, Iran from 2014 to 2016. MATERIALS & METHODS: In this observational cross-sectional study, 71 consecutive children with migraine headache were enrolled. The EEG findings were determined and compared with other variables. RESULTS: There were 25 cases (35.2%) with abnormal EEG and the type of EEG abnormality comprised slow waves and sharp waves in 19(68%) and 8(32%) patients, respectively. CONCLUSION: Nearly one-third of children with migraine might have abnormal EEG.
