TLDR A gene deletion in mice causes weak protein, immune issues, hair loss, airway problems, and wasting disease.
The study investigated mice with a spontaneous deletion in the desmoglein 3 gene, leading to a hypomorphic protein expression. These mice exhibited severe immunodeficiency, cyclic hair loss, obstructed airways, and wasting disease due to oral lesions and malnutrition. Genetic mapping identified a deletion causing a truncated desmoglein 3 protein, which resulted in more severe pathology than complete desmoglein 3 deficiency. This suggests that similar genetic alterations in humans could disrupt desmosome function and cause diseases distinct from pemphigus vulgaris.
