A rare genetic skin disease characterised by generalised skin peeling or superficial blisters without scarring, leukonychia, acral punctate keratoses coalescing into focal keratoderma on the weight-bearing areas, painful angular cheilitis, and knuckle pads with multiple hyperkeratotic micropapules. The skin appears dry and scaly with superficial exfoliation and underlying erythema. Histopathologic examination of affected skin areas is not specific and shows hyperkeratosis, acanthosis, and occasional intraepidermal clefting with irregular acantholysis.

A rare mesomelic and rhizo-mesomelic dysplasia with characteristics of marked mesomelic shortening of the lower limbs, cutaneous syndactyly and nail abnormalities (placed on the palmar side of the finger, dysplastic or absent) in hands and feet due to mutations in EN1 gene. Other clinical features may include genitourinary abnormalities (including bilateral cryptorchidism, vesicoureteral reflux, hydronephrosis, hypoplastic labia majora), spasticity and seizures.

Aplasia of nail unit (disorder)	Finding site	True	Nail unit structure (body structure)	Inferred relationship	Existential restriction modifier (core metadata concept)	1
A rare, isolated nail anomaly characterised by brittle, thin, rough, opaque appearing nails with excessive longitudinal ridging. In a less severe form, the nails retain their luster and present with superficial ridging and multiple small geometric pits. In both varieties, superficial scaling of the nail plate and hyperkeratosis of the cuticles, as well as koilonychia and onychoschizia are observed. Any number of nails may be affected, and fingernails are more often affected than toenails. Spontaneous improvement of the condition may occur.
