- Fever
Peeling skin Intolerance to heat, and may be irritable in warm environments or may have unexplained fevers. More often, diagnosis is not made until the teeth do not erupt at the expected age or the teeth appear to be pointed when they do erupt. [nfed.org]
Because affected infants and children are unable to sweat appropriately when exposed to warm environments, they can experience repeated episodes of heat intolerance and “unexplained” high fevers that may remain unexplained until the disorder is diagnosed [rarediseases.org]

- Hyperthermia
Reduced sweating can lead to a dangerously high body temperature (hyperthermia), particularly in hot weather. In some cases, hyperthermia can cause life-threatening health problems. [ghr.nlm.nih.gov]
Sweating, although present, is greatly deficient, leading to episodes of hyperthermia until the affected individual or family acquires experience with environmental modifications to control temperature. [ncbi.nlm.nih.gov]

- Sparse to No Body Hair
Common symptoms include sparse scalp and body hair, reduced ability to sweat, and missing teeth. HED is caused by mutations in the EDA, EDAR, or EDARADD genes. [rarediseases.info.nih.gov]
Affected individuals tend to have sparse scalp and body hair ( hypotrichosis ). The hair is often light-colored, brittle, and slow-growing. [ghr.nlm.nih.gov]
