July 1999 in “American Journal Of Pathology” This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.
April 2024 in “European Journal of Dermatology” This study suggests that the PPP2R3C gene may confer susceptibility to psoriatic arthritis and psoriasis vulgaris in Chinese patients, with additional possible associations involving IL-23R, ERN1, IFIH1, and KIF3A genes.
