25-year-old woman is blind, because of bilateral congenital optic nerve hypoplasia. She has a long history of fatigue and obesity. Her intelligence is normal. Height is just below the 3rd percentile. Both of her parents Heights are at the 50th percentile. Endocrine evaluation shows, decreased thyroid, stimulating hormone, concentration, and growth, hormone deficiency. Her weight and energy level improved dramatically with thyroid replacement therapy. Which of the following studies is most likely to show a unifying cause of her condition? A) electroretinogram B) iodine uptake C) karyotype D) MRI of the head E) urinary organic acids
