KRT73 (Keratin 73): KRT73 is a gene that encodes a type of keratin protein crucial for the structural integrity of hair and nails. Keratin 73 plays a vital role in the formation of the hair shaft. Alterations or mutations in this gene can impact hair texture and strength, leading to various hair disorders. Research on KRT73 aids in advancing the understanding of hair biology and developing potential therapies for hair-related conditions.
