Article Abstract

Canavan disease (CD) is an inherited leukodystrophy resulting from mutations in the gene encoding aspartoacylase (ASPA). ASPA is highly expressed in oligodendrocytes and catalyzes the cleavage of N-acetylaspartate (NAA) to produce aspartate and acetate. In this review, we examine the pathologies and clinical presentation in CD, the metabolism and transportation of NAA in the brain, and the hypothetical mechanisms whereby ASPA deficiency results in dysmyelination and a failure of normal brain development. We also discuss therapeutic options that could be used for the treatment of CD.

Purpose And Scope: The aim of this position statement is to provide recommendations aimed at Canadian reproductive care clinicians and genetics professionals regarding the use of reproductive carrier screening for autosomal recessive and X-linked recessive conditions.

Methods Of Statement Development: A multidisciplinary expert group was assembled to review the existing literature on reproductive carrier screening for autosomal recessive and X-linked recessive conditions and make recommendations relevant to the Canadian context. The statement was circulated for comment to the membership of the Canadian College of Medical Geneticists (CCMG) and Canadian Association of Genetic Counsellors (CAGC), and multiple family physician reviewers.

Background: Food insecurity and other unmet social needs can contribute to adverse outcomes for mothers and newborns. Food is Medicine (FIM) approaches are promising for improving nutrition and preventing chronic disease but have not been explored fully among rural-dwelling pregnant people. Our objectives were to (1) assess the potential of FIM programs to improve perinatal dietary quality; (2) assess patient satisfaction and self-reported health status with various FIM options; and (3) identify barriers to healthy eating among rural perinatal patients experiencing food insecurity.

Analogous to DNA methylation and protein phosphorylation, it is now well understood that RNA is also subject to extensive processing and modification. N6-methyladenosine (m6A) is the most abundant internal RNA modification and regulates RNA fate in several ways, including stability and translational efficiency. The role of m6A in both experimental and human epilepsy remains unknown.

This case report highlights an atypical presentation of Canavan disease (CD) in a 13-year-old female with intention tremor and fine motor difficulties. Neuroimaging revealed symmetrical changes in various brain regions initially suggesting a neurometabolic or mitochondrial disorder. However, further investigations, including biochemical analysis and whole genome sequencing, confirmed a diagnosis of CD.
