Hypohidrotic ectodermal dysplasia has several different inheritance patterns. Most cases are caused by mutations in the EDA gene, which are inherited in an X-linked recessive pattern. EDAR mutations can have an autosomal dominant or autosomal recessive inheritance pattern, while EDARADD mutations have an autosomal recessive inheritance pattern.
- Individuals with a clinical or suspected diagnosis of hypohidrotic ectodermal dysplasia.
Please note that a "backbone" of probes across the entire genome are included on the array for analytical and quality control purposes. Rarely, off-target copy number variants causative of disease may be identified that may or may not be related to the patient's phenotype. Only known pathogenic off-target copy number variants will be reported. Off-target copy number variants of unknown clinical significance will not be reported.
