Hypotonia, Ataxia, And Delayed Development Syndrome; Hadds
Hypotonia, ataxia, and delayed development syndrome (HADDS) is a neurodevelopmental syndrome characterized by congenital hypotonia, delayed psychomotor development, variable intellectual disability with speech delay, variable dysmorphic facial features, and ataxia, often associated with cerebellar hypoplasia. Some patients may have urogenital abnormalities (summary by Sleven et al., 2017).
