DESSH is short for
DeSanto-Shinawi Syndrome.

DeSanto-Shinawi Syndrome is a rare neurodevelopmental genetic syndrome caused by a mutation or deletion in the WAC gene. DESSH is characterized by global development delay, intellectual disability, hypotonia, dysmorphic facial features, epilepsy, and ocular, gastrointestinal, and behavioral abnormalities. WAC is identified as an autism gene.

DESSH is an autosomal dominant disorder and can be passed down.
