ICD-11 LD27.0 — Ectodermal dysplasia syndromes

Ectodermal dysplasias (EDs) are a heterogeneous group of disorders characterised by developmental dystrophies of ectodermal structures, such as hypohidrosis, hypotrichosis, onychodysplasia and hypodontia or anodontia. More than 160 clinically and genetically distinct hereditary ectodermal dysplasias have been catalogued.
