“…The estimated prevalence of HED is 1-9 in 100,000 individuals and 1 in 5,000-10,000 newborns (Albeik et al, 2023). This disease is characterized by the abnormal development of ectoderm-derived organs, including the absence of sweat glands (anhidrosis or hypohidrosis), scant hair (hypotrichosis), and atypical or absent teeth (anodontia or hypodontia) (Cluzeau et al, 2011;Albeik et al, 2023). HED can be caused by mutations in several genes, which include ectodysplasin A (EDA), ectodysplasin A receptor (EDAR), ectodysplasin A receptor-associated death domain (EDARADD), WNT10A, TRAF6, NEMO, and IKBKG (Nguyen et al, 2021).…”
