There are many different keratin proteins normally expressed in the human integumentary system. Mutations in keratin proteins in the skin can cause disease.

Cutaneous conditions caused by mutations in keratin proteins

Defective keratin type	Condition(s)
1	Epidermolytic hyperkeratosis Ichthyosis hystrix of Curth–Macklin Diffuse nonepidermolytic palmoplantar keratoderma (Unna–Thost keratoderma) Diffuse epidermolytic palmoplantar keratoderma (Vörner keratoderma)
2 (2e)	Ichthyosis bullosa of Siemens
3	Meesmann corneal dystrophy
4	White sponge nevus
5	Epidermolysis bullosa simplex Dowling–Degos' disease Olmsted syndrome
6a	Pachyonychia congenita type I
6b	Pachyonychia congenita type II
7
8
9	Diffuse epidermolytic palmoplantar keratoderma (Vörner keratoderma)
10	Epidermolytic hyperkeratosis Ichthyosis with confetti Ichthyosis hystrix
11
12	Meesmann corneal dystrophy
13	White sponge nevus
14	Epidermolysis bullosa simplex Naegeli–Franceschetti–Jadassohn syndrome Dermatopathia pigmentosa reticularis Olmsted syndrome
15
16	Pachyonychia congenita type I
17	Pachyonychia congenita type II Steatocystoma multiplex Vellus hair cyst
81	Monilethrix
82	Alopecia areata
83	Monilethrix
85	Pure hair–nail type of ectodermal dysplasia
86	Monilethrix

Of note, other structural proteins in the epidermis of the skin that are closely related to keratins may also cause disease if mutated. Examples include:

Cutaneous conditions caused by mutations in structural proteins within the epidermis, excluding keratin proteins

Defective protein	Conditions(s)
Loricrin	Vohwinkel syndrome Progressive symmetric erythrokeratodermia
Filaggrin	Ichthyosis vulgaris Atopic dermatitis
