Klinefelter's syndrome is a genetic condition caused by the presence of an extra X chromosome in males (47, XXY). It leads to underdeveloped testes, resulting in reduced testosterone levels and failure to develop normal male secondary sexual characteristics. This can result in gynecomastia (enlarged breast tissue), poor muscle development, and infertility. A mild intellectual developmental disorder is also commonly seen in individuals with Klinefelter's syndrome. Turner's syndrome (option B) is a genetic condition in females caused by complete or partial absence of one of the X chromosomes, leading to underdeveloped ovaries and infertility. Phenylketonuria (option C) and Tay-Sachs disease (option D) are both genetic disorders that affect nervous system function, but they do not typically present with the symptoms described in the scenario.
