In most cases, uereditaria associated phenotypes i. Pathogenic missense variants give rise to abnormal gene products that may not assemble correctly into functional keratin intermediate filaments.

Genetic basis of Bart’s syndrome: The mechanism of disease is dependent on the variant, but often gain-of-function variants result in protein that prevents proper association with the protein partner krt5-krt14 and assembly of those bullksa dimers into bundles and fibers.
