TLDR FOXN1 mutations cause severe immunodeficiency, hair loss, nail issues, and thymus defects.
The document discussed the human clinical phenotype associated with FOXN1 mutations, which result in severe combined immunodeficiency (SCID) characterized by congenital alopecia, nail dystrophy, and thymic defects. FOXN1, a gene crucial for thymus and skin epithelial cell function, plays a significant role in T-cell development. Mutations in FOXN1 lead to impaired thymocyte maturation, contributing to immunodeficiency. The study highlighted the potential of keratinocytes to support T-cell development in vitro, suggesting a novel role for the skin as a primary lymphoid organ. The chapter focused on the implications of FOXN1 and related FOX gene family members in immunological disorders involving T-cell abnormalities.
