Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common heritable cause of stroke and vascular dementia in adults. We present a family from Serbia presenting with stroke and depression in the lack of vascular risk factors, with brain MRI indicating CADASIL. A novel NOTCH3 Gly89Cys mutation was located in exon 3. This report illustrates that in the setting of a positive family history with typical clinical and MRI features, even with an atypical form of pedigree, a high suspicion of CADASIL should lead to genetic testing. © 2013 Belgian Neurological Society.

Background – Myotonic dystrophy type 1 (DM1) is the most common muscular dystrophy in adults. There is a complete lack of studies that assessed quality of life (QoL) trajectory during time in DM1 cohorts. Aim – To analyze changes of QoL in patients with DM1 during a 5-year follow-up period and to assess responsiveness of the SF-36 questionnaire. Patients and Method – At the baseline, this study comprised 84 DM1 patients, of whom 62 were retested after the mean period of 64.2 ± 3.9 months. Severity of muscular weakness was assessed using the Muscular Impairment Rating Scale (MIRS). Patients completed Serbian version of the SF-36 questionnaire as a measure of health-related QoL. Results – After 5 years, MIRS score of our DM1 patients showed significant progression of 0.5 grade (P < 0.01). All mental subdomains, role physical, and total SF-36 scores significantly improved after 5 years (P < 0.01). Unexpectedly, worsening of muscular weakness from mild to severe was in association with improvement of QoL. Conclusion – QoL improved in our cohort of DM1 patients during a 5-year period despite the progression of the disease. SF-36 should be used with caution as a patient-reported outcome measure in DM1 clinical trials. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd

Mutations in the PARK2 (PRKN) gene are the most common cause of autosomal-recessive (AR) juvenile parkinsonism and young-onset Parkinson's disease (YOPD). >100 different variants have been reported, including point mutations, small indels and single or multiple exon copy number variations. Mutation screening of PARK2 was performed in 225 Serbian PD patients (143 males and 82 females) with disease onset before 50 years and/or positive family history with apparent AR inheritance. All coding regions and their flanking intronic sequences were amplified and directly sequenced. Whole exon multiplications or deletions were detected using Multiple Ligation Probe Amplification (MLPA) method. We identified 12 PD patients with PARK2 mutations (5.3%). Five patients (2.2%) had biallelic mutations and seven (3.1%) were single mutation carriers. Patients with compound heterozygous mutations had earlier onset of the disease compared to non-carriers (p = 0.005) or heterozygotes (p = 0.001). Other clinical features in mutation carriers were not different compared to non-carriers. In our cohort, sequence and dosage variants were equally represented in patients, inducing their first symptoms mainly before the age of 30. For efficient genetic testing strategy, patients with early, especially juvenile onset of PD were strong candidates for both dosage and sequence variants screening of PARK2 gene. © 2018 Elsevier B.V.
