Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...
