A novel online genomic counseling and variant interpretation certificate: Learning design, learning analytics, and evaluation.

In this paper we describe the analysis, planning, design, development, implementation and evaluation of a new online Graduate Certificate in Genomic Counselling and Variant Interpretation (GCGCVI) at The University of British Columbia (UBC). Genetic counselling is now a prerequisite for diagnostic genomic testing in many countries, demanding that genetic counselling practitioners have up-to-the-moment genomic counselling skills and knowledge. Current practitioners reported a desire for more training in this rapidly developing field: our international survey revealed substantial interest in online continuing education addressing themes such as testing and clinical bioinformatics, applied variant interpretation, evidence-based genomic counselling, and other emerging genomic topics.

A personalized genomic results e-booklet, co-designed and pilot-tested by families.

Objective: To develop and evaluate a personalizable genomic results e-booklet that helps families understand their genomic testing results and navigate available resources.

Methods: The need for the Genomics Results e-Booklet was identified by families, after which this tool was developed by a team of clinical researchers and three parent-advisors. We customized the genomic results e-booklet for 50 families participating in a genomic sequencing research study.

Genetic counseling considerations in cerebral palsy.

Genome-wide sequencing (exome and whole genome) has transformed our ability to diagnose patients with suspected genetic disorders. Cerebral palsy (CP), although historically thought to be due to birth injury (perinatal hypoxia), represents a clinical spectrum of disorders, many of which have been attributed to a genetic cause. GWS has elucidated the underlying single gene cause for many patients with CP and has important implications for the customization of treatment, management, and genetic counseling.

Analysis of PGT-M and PGT-SR outcomes at a Canadian fertility clinic.

Objective: Outcomes from in vitro fertilization (IVF)/intrauterine insemination (ICSI) cycles for patients who underwent preimplantation genetic testing for monogenic/single gene (PGT-M) and structural chromosome rearrangements (PGT-SR) patients were reviewed. Patients pursuing PGT-M and PGT-SR often do not have pre-existing fertility issues and therefore may have uncertain expectations of successful outcomes. Before pursuing PGT-M and PGT-SR, patients require evidence-based counseling regarding the probability of having a healthy child.

Frequencies of chromosome-specific mosaicisms in trophoectoderm biopsies detected by next-generation sequencing.

Objective: To examine the chromosome-specific frequencies of mosaicism detected by next-generation sequencing (NGS) compared with constitutional aneuploidy.

Design: Retrospective cross-sectional review of NGS results from trophectoderm biopsies analyzed by per-chromosome prevalence of mosaicism and constitutional aneuploidy.

Setting: Private fertility clinic.

Incidence of Multiple Sclerosis and Related Disorders in Asian Populations of British Columbia.

Background: Global variation in the incidence of multiple sclerosis (MS) is generally ascribed to differences in genetic and environmental risk factors. Here we investigate temporal trends in the incidence of MS and related disorders in British Columbia, Canada, from 1986 to 2010, focusing particularly on the Asian ethnic subpopulation.

Methods: A longitudinal database was screened to identify newly diagnosed cases of MS and related disorders, including neuromyelitis optica and clinically isolated syndromes.

An assessment of genetic counseling services for individuals with multiple sclerosis.

Multiple sclerosis (MS) affects up to 1/500 Canadians. The University of British Columbia MS Clinic (UBC Clinic) is the only MS clinic in Canada (and likely internationally) that routinely offers genetic counseling to patients and their families. A typical session includes the collection of family history and demographic data, discussion of the inheritance of MS, interpretation of family-specific recurrence risks and psychosocial counseling.

Disease-modifying drugs for multiple sclerosis in pregnancy: a systematic review.

Based on fair quality Level 3 evidence, Lu et al.(1) note that glatiramer acetate (GA) exposure was not associated with lower mean birthweight, lower mean gestational age, preterm birth (37 weeks), congenital anomaly, or spontaneous abortion. However, GA was given an indeterminate recommendation because further research is needed.

Association of smoking with risk of multiple sclerosis: a population-based study.

Genetic and environmental factors have important roles in multiple sclerosis (MS) susceptibility. Several studies have shown an association between smoking and MS risk. Here, in a population-based Canadian cohort, we investigate the relationship between personal and maternal smoking exposure and the risk of MS.

Safety of disease-modifying drugs for multiple sclerosis in pregnancy: current challenges and future considerations for effective pharmacovigilance.

When contemplating a pregnancy, women treated for multiple sclerosis (MS) with a disease-modifying drug must decide to discontinue their medication before conception or risk exposing their unborn child to potential drug toxicity. Few studies exist as reference for patients and physicians, and of those available, the majority are less than ideal due to real-world constraints, ethical issues and methodological shortcomings. The authors provide a brief summary of existing animal and human data with current recommendations regarding the safety of IFN-β, glatiramer acetate, natalizumab, mitoxantrone, fingolimod and teriflunomide during pregnancy and lactation in women with MS.

Disease-modifying drugs for multiple sclerosis in pregnancy: a systematic review.

Objective: To systematically review the literature regarding safety of disease-modifying drug (DMD) use during pregnancy on perinatal and developmental outcomes in offspring of patients with multiple sclerosis (MS).

Methods: A PubMed and EMBASE search up to February 2012 was conducted with a manual search of references from relevant articles. Selected studies were evaluated using internationally accepted criteria.

Term pregnancies and the clinical characteristics of multiple sclerosis: a population based study.

Objective: Pregnancy has a well documented effect on relapse risk in multiple sclerosis (MS). Prospective studies have reported a significant decline by two-thirds in the rate of relapses during the third trimester of pregnancy and a significant increase by two-thirds during the first 3 months postpartum. However, it is unclear as to whether there are any long term effects on disability.

Early life child exposure and the risk of multiple sclerosis: a population based study.

The precise aetiology of multiple sclerosis (MS) is yet to be conclusively determined, but both genes and environment and interactions thereof are important. It has been suggested that early life child exposure influences MS susceptibility. Here, in a population-based cohort, we investigated whether infant day care attendance influences the subsequent risk to develop MS.

Congenital abnormalities and multiple sclerosis.

Background: There is a strong maternal parent-of-origin effect in determining susceptibility to multiple sclerosis (MS). One hypothesis is that an abnormal intrauterine milieu leading to impaired fetal development could plausibly also result in increased susceptibility to MS. A possible marker for this intrauterine insult is the presence of a non-fatal congenital anomaly.

Genetic counseling for early-onset familial Alzheimer disease in large Aboriginal kindred from a remote community in British Columbia: unique challenges and possible solutions.

A novel, pathogenic presenilin 1 (PS1) mutation has recently been identified in a large Aboriginal kindred living in dispersed communities throughout British Columbia, Canada. Disseminating genetic information and ensuring that appropriate genetic counseling services are provided to all concerned relatives have posed several unique challenges. These challenges include knowledge exchange and continuity of care in a geographically remote and culturally distinct community.

Accuracy of reported family history and effectiveness of medical record requests in genetic counseling for Alzheimer disease.

The University of British Columbia Hospital Clinic for Alzheimer Disease and Related Disorders (UBCH-CARD) invests significant effort to obtain medical records for the confirmation of patient-reported family histories of dementia. The effectiveness of requesting these records was assessed through a review of the 275 requests made by UBCH-CARD genetic counselors during the 24-month period of January 1, 2005-December 31, 2006. The results were categorized according to outcome.

A novel PS1 gene mutation in a large Aboriginal kindred.

Background: There is currently little information on the genetic epidemiology of Alzheimer disease (AD) among North American Aboriginal populations. No cases of familial AD (FAD) in these populations have been published to date.

Methods: Here, we describe a large North American Aboriginal kindred with early onset FAD (EOFAD) in which genetic testing was done.

Childhood cow's milk allergy and the risk of multiple sclerosis: a population based study.

Autoimmune mechanisms are thought to have a major role in the pathogenesis of multiple sclerosis (MS) and vitamin D is hypothesised to contribute to disease susceptibility. Cow's milk allergy (CMA) is a common childhood allergy arising from an immune system imbalance and can also lead to vitamin D deficiency due to dairy food avoidance. Here, we investigated whether or not CMA influences the subsequent risk to develop MS in a population-based cohort.

No effect of parental age on risk of multiple sclerosis: a population-based study.

Background: Genetic and environmental factors have important roles in multiple sclerosis (MS) susceptibility. A clear parent-of-origin effect has been shown in several populations. Advanced maternal age has been shown to be associated with adverse outcomes in offspring including chromosomal abnormalities.

Parent-of-origin of HLA-DRB1*1501 and age of onset of multiple sclerosis.

Multiple sclerosis (MS) is a complex neurological trait. Allelic variation in the MHC class II region exerts the single strongest effect on MS genetic risk. The clinical onset of the disease is extremely variable, and can range from the first to the ninth decade of life.

Age of onset in concordant twins and other relative pairs with multiple sclerosis.

The ages of onset in multiple sclerosis cases span more than 7 decades. Data are presented for affected relative pairs from a Canadian population base of 30,000 multiple sclerosis index cases (1993-2008). The effects of genetic sharing, parent of origin, intergenerational versus collinear differences, and gender on the ages of onset were evaluated in the following concordant pairs: monozygotic twins (n = 29), dizygotic twins (n = 10), siblings (n = 614), first cousins (n = 405), half siblings (n = 29), parent/child (n = 285), and aunt/uncle/niece/nephew (avunculars) (n = 289).
