Absence of fingerprints-congenital milia syndrome explained

Absence of fingerprints-congenital milia syndrome
Synonyms:Absence of dermatoglyphics congenital milia, Baird syndrome, Adermatoglyphia with congenital facial milia and acral blisters, digital contractures, and nail abnormalities, Basan syndrome.[1]
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
Onset:Birth
Duration:Life-long
Risks:Having a parent with the disorder
Prevention:none
Prognosis:Good
Frequency:extremely rare, only 10 families worldwide are known to be affected with this disorder.

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]

Presentation

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

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]
