Prenatal diagnosis of anhidrotic ectodermal dysplasia with unconventional loci abnormalities： a case report

Anhidrotic ectodermal dysplasia （EDA） is a relatively rare congenital hereditary disease. Because of a reduced number of sweat glands, patients are unable to perspire and consequently suffer from hyperthermia and infection. This is a potential cause of death in childhood. Domestic prenatal diagnosis methods focus on genetic diagnosis. But for some conditions, because of the uncertain molecular pathology, we need other methods to assist to in prenatal diagnosis. Here, we report one case of a new mutation locus which may be associated with EDA and the prenatal diagnosis of EDA by fetal skin biopsy under fetoscopy in mid pregnancy, combined with a review of the literature.
