    TLDR New research has found 14 genes linked to the risk of developing alopecia areata, improving understanding and treatment options.
    Alopecia areata (AA) is an autoimmune condition that leads to hair loss and has a lifetime risk of 2%. It often starts with small, hairless patches and can progress to total body hair loss. The disorder has a genetic component, with a 6-8% recurrence risk in first-degree relatives. It is influenced by both environmental and genetic factors. Recent research has identified 14 genetic susceptibility loci, with many related to immune system genes. The latest genome-wide association, sequencing, and gene expression studies have contributed to understanding AA's genetic basis and have informed new therapeutic approaches.
