To detect gene inversion in two pedigrees affected with Hemophilia A by using Nanopore sequencing technology.

Peripheral blood samples were taken from members of the two pedigrees. Following extraction of genome DNA, genetic variants of the carriers were detected by Nanopore sequencing and subjected to bioinformatic analysis.

Nanopore sequencing has identified the niece of the proband of the pedigree 1 as carrier of Hemophilia A Inv22, and the mother of the proband of the pedigree 2 as carrier of Hemophilia A Inv1, which was consistent with clinical findings. Breakpoint sites in both pedigrees were accurately mapped. Statistical analysis of the sequencing results revealed a large number of variations in the carriers' genomes including deletions, duplications, insertions, inversions and translocations.

Nanopore sequencing can be used to analyze gene inversions associated with Hemophilia A, which also provided a powerful tool for the diagnosis of diseases caused by gene inversions.

This article has summarized the official documents developed and updated by the American College of Medical Genetics and Genomics (ACMG) on governing WES and NIPS. These include the development of expert consensus policies and position statements on an ongoing basis to guide clinical application of NGS technology and variant analysis, establish evidence-based practical resources, as well as standards and guidelines to govern diagnosis and screening. These ACMG documents are valuable references to Chinese geneticists, but direct adoption of these standards and guidelines may not be practical due to the differences in disease-associated variant frequencies in Chinese population, socioeconomic status, and medical practice between the two countries. find more It is hoped that this review could facilitate the development of NGS and NIPS standards and guidelines that are consistent with international standards and concordant with medical genetics practice in China to provide high-quality, efficient and safe clinical services for patients and their families with genetic diseases.With newer research-based classification systems, the term Vascular Cognitive Impairment (VCI) is now preferred to vascular dementia. VCI is an umbrella term that includes all forms of cognitive deficits ranging from mild cognitive impairment of vascular origin (VaMCI) to vascular dementia (VaD). The new VCI construct takes into account the fact that in addition to single strategic infarcts, multiple infarcts, and leukoaraiosis, there are other mechanisms of cerebrovascular disease such as chronic hypoperfusion that might account for the pattern of cognitive deficits associated with vascular dementia. The key to defining the spectrum of VCI is neuropsychological testing, bedside or office-based clinical examination, and neuroimaging. The lack of specific cognitive tools that are sufficiently sensitive to detect subtle deficits makes the assessment of cognitive impairment difficult. Prospective cross-sectional and longitudinal studies of VCI from different settings are therefore required. Although there have been few published reports, behavioural and psychological symptoms (BPS) are inherently present in VCI from the onset and during the course of the disease. Besides the type of population (i.e. clinical, community or nursing-home settings), the definition of VCI/VaD and the instruments used, and differences in the prevalence and pattern of BPS between various studies, could be due to other, often unconsidered, factors such as gender, age, education, use of medication and VCI/VaD severity.

The pandemic state of COVID-19 has resulted in new neurological post-infection syndromes. Recently, several papers have reported ataxia-myoclonus syndrome following SARS-CoV-2 infection. The aim of this study was to present our two cases and compare them to previously reported cases.

We present two video-accompanied new cases with ataxia-myoclonus syndrome following SARS-CoV-2 infection and discuss the studies published so far.

Ataxia-myoclonus syndrome, isolated myoclonus, opsoclonus-myoclonus syndrome as post-COVID-19 syndrome following infection have been described in 16 patients (including our two cases). Patients have been treated with intravenous immunoglobulins and/or steroids except for 4 patients, which resulted in a significant improvement within 1-8 weeks.

The increasing number of patients with a similar symptomatology shows a significant relationship between COVID-19 infection and ataxia-myoclonus syndrome. The subacute onset of neurological symptoms after a resolved COVID-19 infection and prominent response to immunotherapy may suggest that the neurological manifestations are immune-mediated. Although recovery is highly possible, it may take several weeks/months, and clinicians should be aware of this diagnosis and the beneficial effects of immunological treatment administered as soon as possible.

Several de-escalation strategies of antiplatelet treatment aiming to enhance safety of DAPT without depriving it of its efficacy have been evaluated so far. We hypothesized that reduction of the ticagrelor maintenance dose 1 month after ACS and its continuation until 12 months after ACS may improve adherence to antiplatelet treatment due to better tolerability compared with the standard dose of ticagrelor. Moreover, improved safety of treatment and preserved anti-ischemic benefit may also be expected with additional acetylsalicylic acid (ASA) withdrawal. To evaluate these hypotheses, we designed the Evaluating Safety and Efficacy of Two Ticagrelor-based De-escalation Antiplatelet Strategies in Acute Coronary Syndrome - a randomized clinical trial (ELECTRA-SIRIO 2), to assess the influence of ticagrelor dose reduction with or without continuation of ASA versus DAPT with standard dose ticagrelor in reducing clinically relevant bleeding and maintaining anti-ischemic efficacy in ACS patients.
