Sweat testing to identify female carriers of X linked hypohidrotic ectodermal dysplasia.
X linked hypohidrotic ectodermal dysplasia (XHED) affects many epithelial functions, including sweat gland formation. Female carriers who manifest XHED may have defective dentition or a patchy distribution of sweating or both, as determined by starch and iodine sweat testing. Such sweat testing can be useful in assigning carrier status to at risk females in XHED families, and in obtaining an ac...
متن کاملPossible genetic heterogeneity in X linked hypohidrotic ectodermal dysplasia.
Hypohidrotic ectodermal dysplasia has been mapped to Xq11-q13 by linkage studies and by a translocation in a manifesting female. We report a family with hypohidrotic ectodermal dysplasia in which the disease did not segregate with this region of the X chromosome as expected. Ten DNA probes which are localised between Xp11 and Xq22 were used in the investigation. The difficulties in diagnosing t...
متن کاملLung and eye involvement in X-linked hypohidrotic ectodermal dysplasia
Objective X-linked hypohidrotic ectodermal dysplasia (XLHED; ectodysplasin deficiency) has been classically described as affecting hair, sweat glands and dentition. What may be underappreciated is the effect ectodysplasin deficiency has on glands surrounding the airways and eyes and the resulting chronic health issues. In this study, we evaluated respiratory and ocular symptoms in XLHED patients.
متن کاملClinical aspects of X-linked hypohidrotic ectodermal dysplasia.
Boys with X-linked hypohidrotic ectodermal dysplasia and their families were studied. Many suffered severe illness in early childhood and nearly 30% died; many had feeding problems, severe fever, atopic disease, and recurrent respiratory infections. Some infants failed to thrive. We found no consistent common endocrine or immunological abnormality, although, most had abnormal immunoglobulin pro...
متن کاملMethylation State of the EDA Gene Promoter in Chinese X-Linked Hypohidrotic Ectodermal Dysplasia Carriers
INTRODUCTION Hypodontia, hypohidrosis, sparse hair and characteristic faces are the main characters of X-linked hypohidrotic ectodermal dysplasia (XLHED) which is caused by genetic ectodysplasin A (EDA) deficiency. Heterozygous female carriers tend to have mild to moderate XLHED phenotype, even though 30% of them present no obvious symptom. METHODS A large Chinese XLHED family was reported an...
