The pre-existing partial dislocation (green atoms at far end) in the twin boundary prevents absorption through the long-range elastic interaction with the impinging screw. Atoms are colored by the central symmetry parameter. See the article by Zhu et al. on pages 3031–3036. Image courtesy of Ting Zhu, Ju Li, and Subra Suresh.

  • KIF1A-Related Autosomal Dominant Spastic Paraplegias (SPG30) in Russian Families G
    Rudenskaya et al. BMC Neurology (2020) 20:290 https://doi.org/10.1186/s12883-020-01872-4 RESEARCH ARTICLE Open Access KIF1A-related autosomal dominant spastic paraplegias (SPG30) in Russian families G. E. Rudenskaya1 , V. A. Kadnikova1* , O. P. Ryzhkova1 , L. A. Bessonova1, E. L. Dadali1 , D. S. Guseva1 , T. V. Markova1 , D. N. Khmelkova2 and A. V. Polyakov1 Abstract Background: Spastic paraplegia type 30 (SPG30) caused by KIF1A mutations was first reported in 2011 and was initially considered a very rare autosomal recessive (AR) form. In the last years, thanks to the development of massive parallel sequencing, SPG30 proved to be a rather common autosomal dominant (AD) form of familial or sporadic spastic paraplegia (SPG),, with a wide range of phenotypes: pure and complicated. The aim of our study is to detect AD SPG30 cases and to examine their molecular and clinical characteristics for the first time in the Russian population. Methods: Clinical, genealogical and molecular methods were used. Molecular methods included massive parallel sequencing (MPS) of custom panel ‘spastic paraplegias’ with 62 target genes complemented by familial Sanger sequencing. One case was detected by the whole -exome sequencing. Results: AD SPG30 was detected in 10 unrelated families, making it the 3rd (8.4%) most common SPG form in the cohort of 118 families. No AR SPG30 cases were detected. In total, 9 heterozygous KIF1A mutations were detected, with 4 novel and 5 known mutations. All the mutations were located within KIF1A motor domain. Six cases had pure phenotypes, of which 5 were familial, where 2 familial cases demonstrated incomplete penetrance, early onset and slow relatively benign SPG course.
