General annotation (Comments)

Subunit structure	Heterotetramer of two type I and two type II keratins.
Tissue specificity	Synthesis begins in the cortex 10-15 cell layers above the apex of the dermal papilla and ends abruptly in the middle of the cortex. Ref.1
Involvement in disease	Defects in KRT83 are a cause of Monilethrix [MIM:158000]. Monilethrix is an autosomal dominant hair disorder characterized clinically by alopecia and follicular papules. Affected hairs have uniform elliptical nodes of normal thickness and intermittent constrictions, internodes at which the hair easily breaks. Usually only the scalp is involved, but in severe forms, the secondary sexual hair, eyebrows, eyelashes, and nails may also be affected. Ref.5
Miscellaneous	There are two types of hair/microfibrillar keratin, I (acidic) and II (neutral to basic).
Sequence similarities	Belongs to the intermediate filament family.
Caution	Maps to a duplicated region on chromosome 12.
