Q. A 2-month-old male infant was brought to the clinic for evaluation of poor feeding and excessive weight loss. Upon examination, the infant was found to have a weight of 4.5 kg (10th percentile) and a length of 60 cm (50th percentile). Blood pressure was elevated at 140/100 mmHg. The infant was born full-term via vaginal delivery with a birth weight of 3.8 kg. The pregnancy was complicated by gestational diabetes and hypertension. There is no significant family history of endocrine disorders. The infant had normal male genitalia. There was no evidence of acne, hirsutism, or alopecia. The abdomen was protuberant with no hepatosplenomegaly. Initial laboratory studies showed elevated serum 17-hydroxyprogesterone and 11-deoxycorticosterone levels with decreased serum cortisol levels. Aldosterone and renin levels are also decreased. What is the most likely diagnosis?
