In this study, researchers created a mouse model using CRISPR/Cas9 technology to investigate hypotrichosis simplex and woolly hair, finding that Krt71-knockout mice exhibited curly hair and developed complete hair shedding without immune deficiencies, mimicking conditions seen in humans and potentially aiding future hair disorder research.

August 2014 in “Veterinary Dermatology” This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.

July 2021 in “Genes” This study identified a new genetic variant in the KRT71 gene responsible for a breed-specific form of hypotrichosis in Hereford cattle, potentially serving as a model for similar human conditions.

March 2012 in “Journal of biological chemistry/The Journal of biological chemistry” In this study, researchers found that overexpression of the hairless protein in Hr mutant mice disrupts inner root sheath formation by downregulating Dlx3 and associated keratins in hair follicle development.
April 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, the researchers introduced a mutation in mice to mimic Olmsted syndrome and found that the mutation caused hair loss due to impaired keratinocyte differentiation and depletion of hair follicle stem cells.
