All are features of hypohidrotic ectodermal dysplasia EXCEPT:

Adrenal gland dysfunction
Anhidrosis
Hypotrichosis (sparse hair)
Hypodontia or anodontia

Show answer and explanation

Correct answer: A. Adrenal gland dysfunction

Ectodermal dysplasia affects ectoderm-derived structures: teeth, hair, sweat glands, skin. ADRENAL GLAND DYSFUNCTION is NOT a feature — adrenal cortex is mesodermal, medulla is neural crest. Dry skin, periorbital wrinkling are also classic features.
