Regression
Gene: ST3GAL5
Salt and pepper developmental regression syndrome, also known as Amish infantile epilepsy syndrome, is an autosomal recessive neurocutaneous disorder characterised by infantile onset of refractory and recurrent seizures associated with profoundly delayed psychomotor development and/or developmental regression as well as abnormal movements and visual loss. Affected individuals develop hypo- or hyperpigmented skin macules on the trunk, face, and extremities in early childhood. Although initially reported in the Amish (founder variant p.Arg288Ter), families from other ethnicities have also been reported.
