Absence of fingerprints-congenital milia syndrome

Absence of fingerprints-congenital milia syndrome, also known as Baird syndrome or adermatoglyphia with congenital facial milia, is an extremely rare genetic skin disorder characterized by the congenital absence of dermatoglyphics (fingerprints, as well as palm prints and sole prints) combined with the presence of milia — small, white, keratin-filled cysts — that are typically present on the face at birth or early infancy. The condition primarily affects the integumentary system (skin). Affected individuals are born without the normal epidermal ridge patterns on the fingers, palms, and soles, a feature that can cause practical difficulties with biometric identification systems. The facial milia may diminish over time but can also persist. Additional features reported in some cases include reduced sweating on the palms and soles and blistering of the skin, particularly in areas subject to friction. This syndrome was first described in a small number of families, and the genetic basis has been linked to mutations in the SMARCAD1 gene (specifically in a skin-specific isoform), which plays a role in chromatin remodeling and skin development. The condition follows an autosomal dominant inheritance pattern with variable expressivity. There is currently no specific curative treatment for this syndrome. Management is supportive and symptomatic, focusing on skin care for milia (which may resolve spontaneously or can be treated with minor dermatological procedures) and addressing any complications related to reduced sweating or skin fragility. Genetic counseling is recommended for affected families.
