Absence of fingerprints-congenital milia syndrome

(Redirected from Basan syndrome)

Absence of fingerprints-congenital milia syndrome, also known simply as Baird syndrome is an extremely rare autosomal dominant genetic disorder which is characterized by a lack of fingerprints and the appearance of blisters and facial milia soon after birth.[2] It has been described in ten families worldwide.[3][4]

Absence of fingerprints-congenital milia syndrome
Other namesAbsence of dermatoglyphics congenital milia, Baird syndrome, Adermatoglyphia with congenital facial milia and acral blisters, digital contractures, and nail abnormalities, Basan syndrome.[1]
SpecialtyMedical genetics
Symptomsadermatoglyphia with neo-natal blisters and facial milia
ComplicationsUsually 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 onsetBirth
DurationLife-long
TypesAdermatoglyphia syndromes
CausesGenetic mutation
Risk factorsHaving a parent with the disorder
Diagnostic methodPhysical examination, genetic testing
Differential diagnosisIsolated adermatoglyphia
Preventionnone
PrognosisGood
Frequencyextremely rare, only 10 families worldwide are known to be affected with this disorder.

Presentation

edit

People with this disorder often have congenital adermatoglyphia, facial milia and blisters soon after birth, hypohidrosis (less sweating than average), and either thin or thickened skin throughout the body.[5][6][7][8]

Single transversal palmar lines, plantar keratoderma, nail grooving, toe syndactyly and finger camptodactyly have also been reported.[9][10][11] Rarely, constriction ring syndrome is reported.[12]

Causes

edit

Through a large Han Chinese family with the disorder, it was found to be caused by mutations in the SMARCAD1 gene, in chromosome 4.[13][14][15][16][17][18][19] This gene produces a protein that is believed to control genes associated with the development of the fingerprints.[20]
