PAX2 (Paired Box Gene 2): PAX2 is a crucial transcription factor in the paired box gene family, playing an essential role in the development of the kidneys and the urinary tract. It acts early in the embryonic stages to regulate the formation of tissues and organs, guiding the development of the renal system, eye, ear, and central nervous system. By influencing cell proliferation, differentiation, and apoptosis, PAX2 helps in the formation of essential structures within these systems. Aberrations in PAX2 expression or function have been linked to congenital anomalies of the kidney and urinary tract (CAKUT), as well as to...
