Inborn errors of metabolism (IEM) are a heterogenous group of rare, inherited disorders that impair the biochemical processes involved in metabolism. Many are treated with various restrictive diets in early infancy, prior to the appearance of symptoms to improve the overall outcomes of the affected individuals. Identification of individuals at a risk of developing metabolic disorders through newborn screening (NBS) programs and the subsequent early diagnosis and treatment are an invaluable aspect of healthcare in Canada. Incorporation of Canada’s expanding population of refugees and new immigrants presents with potential challenges and changes. Without the availability of NBS programs in many countries contributing to the refugee influx in Canada, it may be difficult to identify patients who are affected with these rare conditions. This article discusses: 1) the utility of newborn screening and diagnosis of metabolic diseases in immigrant and refugee populations, with complex medical presentations, and 2) a recent diagnosis of succinic semialdehyde dehydrogenase deficiency (an IEM) in a refugee child past the age limit of NBS. An increasingly complicated and diverse refugee population requires a need for revision of existing healthcare practices pertaining to the diagnosis of rare diseases.
