Aberrant Splicing Caused by a Novel VPS16 Variant Linked to Dystonia Type 30.
Dystonia is a hyperkinetic movement disorder characterized by sustained or intermittent involuntary muscle contractions, causing abnormal postures and/or repetitive movements. In this report, we identified a novel heterozygous splice-site variant in VPS16 (NM_022575.4:c.240+3G>C) in a patient with cervical and upper limb dystonia without other neurological or extra-neurological features. Analysis of patient's blood mRNA showed disruption of exon 3/intron 3 donor splice-site, leading to exon 3 skipping, which predictably results in a frameshift [p.(Ala48Valfs*14)]. Despite the scarcity of splice-affecting variants described in VPS16-related dystonia, our report contributes with the first fully characterized variant at the mRNA level.
期刊介绍：
Neurogenetics publishes findings that contribute to a better understanding of the genetic basis of normal and abnormal function of the nervous system. Neurogenetic disorders are the main focus of the journal. Neurogenetics therefore includes findings in humans and other organisms that help understand neurological disease mechanisms and publishes papers from many different fields such as biophysics, cell biology, human genetics, neuroanatomy, neurochemistry, neurology, neuropathology, neurosurgery and psychiatry.
All papers submitted to Neurogenetics should be of sufficient immediate importance to justify urgent publication. They should present new scientific results. Data merely confirming previously published findings are not acceptable.
