This study found that wire brush hair snares collected the most hair from Eurasian Lynx in controlled enclosures, suggesting potential for sampling genetic material from similar felid species.

This case study highlights the complexity of managing autoimmune polyglandular syndrome type 1, emphasizing the need for thorough clinical history, high suspicion for early diagnosis, and continuous long-term follow-up.

This article outlines methods to study the skin and its molecular traits, focusing on interpretation and techniques applicable to mouse models, including diverse assays and approaches like electron microscopy and large-scale lipid analyses.

This study examined the genetic basis of alopecia areata by analyzing gene expression differences between patients and healthy controls, identifying critical pathways, hub genes, transcription factors, and miRNAs implicated in the disease, and suggesting potential targets for treatment.

In this case study, an 8-year-old boy with alopecia totalis experienced significant hair regrowth after baricitinib treatment, suggesting KRT74 variants may influence immune dysregulation in this condition.

This study explores hypertrichosis, a condition of excessive hair growth, highlighting its classification, diagnostic methods, and potential treatments. The authors emphasize the importance of individualized approaches and further genetic research to enhance treatment options for this primarily cosmetic issue that can signal systemic diseases.

In this study, researchers identified a rare form of hereditary hypotrichosis linked to mutations in the LSS gene, which affects cholesterol biosynthesis and is inherited in an autosomal recessive manner.

This study reports the first case of mandibuloacral dysplasia syndrome associated with MTX2 gene mutation in the Chinese population, expanding the known spectrum of MTX2 mutations.
