Adermatoglyphia is an extremely rare genetic disorder that prevents the development of fingerprints. Five extended families worldwide are known to be affected by this condition. Five extended families worldwide are known to be affected by this condition.
adermatoglyphia with neo-natal blisters and facial milia: Complications: Usually none (health-wise), however; hypohidrosis may lead to heat exhaustion or even a heat stroke, and the absence of fingerprints may complicate the use of systems that require fingerprint-identification: Usual onset: Birth: Duration: Life-long: Types: Adermatoglyphia ...
Most cases are caused by mutations in the EDA gene, which are inherited in an X-linked recessive pattern, called x-linked hypohidrotic ectodermal dysplasia (XLHED). A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes.
Dermatoglyphics, when correlated with genetic abnormalities, aids in the diagnosis of congenital malformations at birth or soon after.. Klinefelter syndrome: excess of arches on digit 1, more frequent ulnar loops on digit 2, overall fewer whorls, lower ridge counts for loops and whorls as compared with controls, and significant reduction of the total finger ridge count.
A mutation in SOX10, the gene involved in type 2E and type 4C, can sometimes result in the symptoms of both types (neurological symptoms, as sometimes seen in type 2E, and Hirschsprung's disease, as seen in type 4). When this happens, it is called peripheral demyelinating neuropathy–central dysmyelinating leukodystrophy–Waardenburg syndrome ...
Naegeli–Franceschetti–Jadassohn syndrome (NFJS), also known as chromatophore nevus of Naegeli and Naegeli syndrome, [1] [2] is a rare autosomal dominant [3] form of ectodermal dysplasia, characterized by reticular skin pigmentation, diminished function of the sweat glands, the absence of teeth and hyperkeratosis of the palms and soles.
Amid mounting fears over the potentially deadly diseases the creatures can spread, one mother is raising concerns about a type of tick so small most people wouldn't be able to spot it on their own ...
Dermatopathia pigmentosa reticularis (DPR) is a rare, autosomal dominant [2] congenital disorder that is a form of ectodermal dysplasia.Dermatopathia pigmentosa reticularis is composed of the triad of generalized reticulate hyperpigmentation, noncicatricial alopecia, and onychodystrophy. [3]
