    Abstract Background: There is limited data on the utility, yield, and cost efficiency of genetic testing in adults with epilepsy. We aimed to describe the yield and utility of genetic panels in our adult epilepsy clinic.
    Methods: We performed a retrospective, cross-sectional study of all patients followed by an epileptologist at a Canadian tertiary care centre's epilepsy clinic between January 2016 and August 2021 for whom a genetic panel was ordered. A panel was generally ordered when the etiology was unknown or in the presence of a malformation of cortical development. We determined the yield of panel positivity and of confirmed genetic diagnoses. We also estimated the proportion of these diagnoses that were clinically actionable.
    Results: In total, 164 panels were ordered in 164 patients. Most had refractory epilepsy (80%), and few had comorbid intellectual disability (10%) or a positive family history of epilepsy (11%). The yield of panel positivity was 11%. Panel results were uncertain 49% of the time and negative 40% of the time. Genetic diagnoses were confirmed in 7 (4.3%) patients. These genetic conditions involved the following genes:
    Conclusion: We report a lower diagnostic yield for genetic panels in adults with epilepsy than what has so far been reported. Although the field of the genetics of epilepsy is a fast-moving one and more data is required, our findings suggest that guidelines for genetic testing in adults are warranted.

    Abstract Turner syndrome (TS) occurs in one in 2500 live female births and is one of the most common chromosomal abnormalities in women. Pregnancies in women with TS, conceived with either autologous or donated oocytes, are considered high risk because of the associated miscarriages and life-threatening cardiovascular complications (aortic dissection, severe hypertension). Therefore, it is imperative to conduct a full preconception evaluation and counselling that includes cardiac assessment with Holter blood pressure monitoring, echocardiography, and thoracic MRI. Abnormal findings, such an aortic dilatation, mandate close monitoring throughout the pregnancy and the immediate postpartum period and could possibly contraindicate pregnancy. When in vitro fertilization using donated oocytes is performed in these women, only a single embryo should be transferred. Women with a Turner mosaic karyotype appear to have a lower risk of obstetrical and cardiovascular complications but should nevertheless undergo the full preconception evaluation. In this article, we offer guidelines on the management of women with TS in the preconception period, during pregnancy, and postpartum.
