Presentation
The affected members present with sparse and woolly hair, severe nail dystrophy and reticulate skin pigmentation. [paperity.org]
Classification of these conditions often presents many nosological challenges, since underlying etiologies and pathogenetics are often not known. [howlingpixel.com]
Pathogenic sequence variant identified here is present in heterozygous conditions in both healthy siblings and a mother. This mutation is a pathogenic, and not present outside the family because we screened 102 ethnically match control individuals. [bmcmedgenet.biomedcentral.com]
Most patients in the present study were males and presented HED, which usually is the most severe type as to the occurrence of dental abnormalities. [ijdr.in]
We present a child evaluated in a multidisciplinary manner with clinical and molecular diagnosis of X-linked hypohidrotic ectodermal dysplasia with type missense mutation c.1133C> T; p.T378M in EDA gene. [moh-it.pure.elsevier.com]
Skin
- Alopecia
ECTD4 is characterized by complete alopecia, hypotricosis and nail dystrophy in all digits. There is no evidence of any other abnormality. Inheritance can be autosomal dominant or recessive. [uniprot.org]
'pure' hair-nail type Clinical features : Imported from Human Phenotype Ontology (HPO) Abnormality of head or neck Abnormality of the teeth Absent eyebrow Abnormality of the integument Abnormality of the sweat gland Absent eyebrow Absent eyelashes Alopecia [familydiagnosis.com]
Patients show complete alopecia and primitive nails. Autosomal recessive type has previously been associated with mutations in either KRT85, KRT74 or HOXC13. [genome.jp]

Prognosis
Prognosis The prognosis for most patients with ectodermal dysplasia is very good. Morbidity and mortality is related to the absence or dysfunction of eccrine and mucous glands. [emedicine.medscape.com]
Etiology
Classification of these conditions often presents many nosological challenges, since underlying etiologies and pathogenetics are often not known. [howlingpixel.com]
Genetic studies regarding the etiology of EDA revealed that mutations in the ectodysplasin-A and ectodysplasin-A receptor genes are responsible for X-linked and autosomal hypohidrotic ectodermal dysplasia [5]. [ijcasereportsandimages.com]
Although some ectodermal dysplasia syndromes have no known genetic etiology, the number of ectodermal dysplasia syndromes with an identifiable genetic basis is increasing. [emedicine.medscape.com]
Abstract quote Focal palmoplantar and gingival keratosis is a rare autosomal dominant disease whose clinical features, and in particular, pathologic alterations and molecular etiology remain to be well defined. [thedoctorsdoctor.com]

Various classifications have been proposed based on clinical features, mode of inheritance, gene mutations and pathophysiology, but pure EDA manifests with defects in ectodermal structures alone. [ijcasereportsandimages.com]
Pathophysiology Ectodermal dysplasia results from the abnormal morphogenesis of cutaneous and/or oral embryonal ectoderm (ie, hair, nails, teeth, eccrine glands). In some forms, mesodermal abnormalities are also present. [emedicine.medscape.com]
