Isolated congenital adermatoglyphia is a rare, genetic developmental defect during embryogenesis disorder characterized by the lack of epidermal ridges on the palms and soles, resulting in the absence of fingerprints, with no other associated manifestations. It is associated with a reduced number of sweat gland openings and reduced transpiration of palms and soles. [from ORDO]

Complete congenital absence of dermatoglyphs is a rare syndrome characterized by autosomal dominant inheritance of the lack of ridges on palms and soles, neonatal acral blisters and facial milia, adult traumatic blistering and fissuring, absent or reduced sweating of palms and soles, and contracture of digits. Additional features may include single palmar transverse crease, palmoplantar keratoderma, and nail grooving (summary by Limova et al., 1993). [from OMIM]

Huriez syndrome (HRZ) is characterized by the triad of congenital scleroatrophy of the distal extremities, palmoplantar keratoderma, and hypoplastic nail changes. The development of aggressive squamous cell carcinoma (SCC) in areas of affected skin is a distinctive feature of the syndrome, occurring in approximately 15% of patients. HRZ-associated SCC shows early onset, mostly in the third to fourth decades of life, and early metastasis formation (summary by Lee et al., 2000). See also 610644 for description of a disorder resembling Huriez syndrome, involving palmoplantar hyperkeratosis and squamous cell carcinoma in association with SRY (480000)-negative female-to-male XX sex reversal, caused by mutation in the RSPO1 gene (609595). [from OMIM]
