Final answer:
Partial enzyme deficiencies in congenital adrenal hyperplasia can present with salt-losing symptoms, ambiguous genitalia, poor growth, and hyperpigmentation during childhood.
Step-by-step explanation:
Partial enzyme deficiencies in congenital adrenal hyperplasia can present with various signs and symptoms during childhood.
Salt-losing forms of congenital adrenal hyperplasia can cause excessive loss of sodium and chloride, leading to dehydration, low blood pressure, and electrolyte abnormalities.
Ambiguous genitalia may be present in affected females due to abnormal hormone production and virilization.
Poor growth and delayed puberty are common manifestations of congenital adrenal hyperplasia
Hyperpigmentation may occur due to increased production of adrenocorticotropic hormone (ACTH), leading to melanin synthesis and deposition.
In summary, during childhood, partial enzyme deficiencies in congenital adrenal hyperplasia may present with salt-losing symptoms, poor growth, and hyperpigmentation.
