Neurodevelopmental profiles of 14 individuals with phosphomannomutase deficiency (PMM2-CDG).
PMM2-CDG (formerly CDG-1a), the most common type of congenital disorders of glycosylation, is inherited in an autosomal recessive pattern. PMM2-CDG frequently presents in infancy with multisystemic clinical involvement, and it has been diagnosed in over 1000 people worldwide. There have been few natural history studies reporting neurodevelopmental characterization of PMM2-CDG. Thus, a prospective study was conducted that included neurodevelopmental assessments as part of deep phenotyping. This study, Clinical and Basic Investigations into Known and Suspected Congenital Disorders of Glycosylation (NCT02089789), included 14 participants (8 males and 6 females ages 2-33 years) with a confirmed molecular diagnosis of PMM2-CDG. Clinical features of PMM2-CDG in this cohort were neurodevelopmental disorders, faltering growth, hypotonia, cerebellar atrophy, peripheral neuropathy, movement disorders, ophthalmological abnormalities, and auditory function differences. All PMM2-CDG participants met criteria for intellectual disability (or global developmental delay if younger than age 5). The majority never attained certain gross motor and language milestones. Only two participants were ambulatory, and almost all were considered minimally verbal. Overall, individuals with PMM2-CDG present with a complex neurodevelopmental profile characterized by intellectual disability and multisystemic presentations. This systematic quantification of the neurodevelopmental profile of PMM2-CDG expands our understanding of the range in impairments associated with PMM2-CDG and will help guide management strategies.
期刊介绍:
The Journal of Inherited Metabolic Disease (JIMD) is the official journal of the Society for the Study of Inborn Errors of Metabolism (SSIEM). By enhancing communication between workers in the field throughout the world, the JIMD aims to improve the management and understanding of inherited metabolic disorders. It publishes results of original research and new or important observations pertaining to any aspect of inherited metabolic disease in humans and higher animals. This includes clinical (medical, dental and veterinary), biochemical, genetic (including cytogenetic, molecular and population genetic), experimental (including cell biological), methodological, theoretical, epidemiological, ethical and counselling aspects. The JIMD also reviews important new developments or controversial issues relating to metabolic disorders and publishes reviews and short reports arising from the Society''s annual symposia. A distinction is made between peer-reviewed scientific material that is selected because of its significance for other professionals in the field and non-peer- reviewed material that aims to be important, controversial, interesting or entertaining (“Extras”).
