    No significant differences between gBRCA2 carriers and non-carriers were observed in the prevalence of IDC (36% gBRCA2 versus 50% non-carriers, p=0.085) or CRIB (53% gBRCA2 versus 43% non-carriers p=0.197) patterns. However, IDC histology was independently associated with bi-allelic BRCA2 alterations (OR 4.3, 95%CI 1.1-16.2) and PTEN homozygous loss (OR 5.2, 95%CI 2.1-13.1). CRIB morphology was also independently associated with bi-allelic BRCA2 alterations (OR 5.6, 95%CI 1.7-19.3).

    While we found no association between gBRCA2 mutations and IDC or CRIB histologies, bi-allelic BRCA2 loss in primary prostate tumours was significantly associated with both variant morphologies, independently of other clinical-pathologic factors.

CEP290 mutations have been linked to numerous ciliopathies, with a wide range of phenotypic severities, but with poor genotypephenotype correlation. Here we have used CRISPR/Cas9 technology to target the CEP290 gene and generate a line of induced pluripotent stem cells that lack detectable CEP290 expression, but retain a normal karyotype and differentiation potential. This line of cells will be useful for the study of disorders resulting from CEP290 mutations.The UMi028-A-2 human induced pluripotent stem cell line carries a homozygous mutation (rs377155188, C>G, p.S1038C) in the tetratricopeptide repeat domain 3 (TTC3) gene that was introduced via CRISPR/Cas9 genome editing. The line was originally derived from a neurologically normal male and has been thoroughly characterized following editing. The p.S1038C variant has been shown to potentially contribute to the risk of late onset Alzheimer’s disease and is a resource to further investigate the consequences of TTC3 and this alteration in disease pathology.Here, we describe the generation of an induced pluripotent stem cell (iPSC) line, from a female patient diagnosed with Parkinson’s disease (PD). The patient carries a heterozygous intermediate-length GGC repeat expansions mutation in the NOTCH2NLC gene. SMIP34 Skin fibroblasts were reprogrammed using the non-integrating Sendai virus technology to deliver Klf4, OCT3/4, SOX2 and c-MYC factors. The generated iPSC line (ZZUi020-A) presented with expression of common pluripotency markers, showed potential of differentiating into derivatives of the three germ layers, and displayed a normal karyotype. The clone ZZUi020-A is presented thereafter, it can be used to study the mechanisms underlying NOTCH2NLC-PD pathogenesis.

    Acute withdrawal of antiepileptic drugs (AEDs) is a safe and effective approach to provoking seizures in order to complete video-electroencephalogram (V-EEG) studies in a timely manner. Previous studies have focused only on withdrawal from conventional AEDs, and the effects of withdrawal from new-generation AEDs have not been extensively studied.

    This study examined adult patients with drug-resistant epilepsy admitted to an epilepsy monitoring unit between 2015 and 2018. Patients were classified according to whether they received conventional AEDs (Con; n = 13) or new-generation AEDs (N-Gen; n = 26). We then compared the effects of withdrawing these two types of AEDs over a period of one week in terms of efficacy (time to complete V-EEG monitoring) and safety, including the incidence of cluster seizures (CS), focal to bilateral tonic-clonic seizures (FBTCS) and status epilepticus (SE).

    In both groups, approximately one week was required to complete V-EEG analysis N-Gen group (5.6 days) and Con group (6.V-EEG monitoring within one week.

    To examine perspectives of adult patients with epilepsy, caregivers, and healthcare professionals (HCPs) on seizure freedom, seizure control, communication, and treatment goals.

    Participants were recruited from online M3 panel and by Rare Patient Voice, and completed the self-administered online STEP Survey (Seize the Truth of Epilepsy Perceptions). Group comparisons used analysis of variance and chi-square tests.

    The STEP Survey was completed by 400 adult patients with epilepsy, 201 caregivers, and 258 HCPs (112 general neurologists, 96 epileptologists, 50 nurse practitioners/physician assistants). Significantly more patients (61%) and caregivers (66%) than HCPs (45%) agreed that seizure freedom is always a reasonable goal (P < 0.05). On average, patients considered 3.6 seizures/year to be “in control.” Of their patients with focal seizures, HCPs reported 47% were seizure-free and 33% were “in control” (63% were having 1-12 seizures/year), and 20% were with “uncontrolled” seizures. Among patients, cignment of goals among patients with epilepsy, caregivers, and HCPs.

    Differing perspectives on seizure freedom, seizure control, communication priorities, and treatment goals that were identified in the STEP Survey provide opportunities to improve patient care and outcomes through more effective two-way communication and alignment of goals among patients with epilepsy, caregivers, and HCPs.

    Treatment with antiseizure medications (ASMs) confers a risk of drug-induced liver injury (DILI), especially for older ASMs. We sought to quantify recent reports of DILI attributed to both older and newer generation ASMs and survey newly marketed ASMs for hepatotoxicity in a large post-marketing database.

    We queried over 2.6 million adverse event reports made to the FDA Adverse Event Reporting System (FAERS) database between July 1, 2018 and March 31, 2020 for DILI due to ASMs commonly used in clinical practice. Patient characteristics and outcomes were assessed. We calculated the reporting odds ratio (ROR) of DILI for each individual ASM versus all non-ASM reports.

    A total of 2175 DILI cases were attributed to an ASM during the study period. 97.2% of these were designated as serious reactions, which include death, hospitalization, disability, and other life-threatening outcomes. A number of older and newer generation ASMs were associated with DILI, specifically carbamazepine (ROR 2.92), phenobarbital (ROR 2.
