She states that, although shorter, he had been growing at the same rate as his peers until the past year. There is no evidence of delayed puberty in the mother, but the fathers history is unknown. The patient has no complaints. On physical exam, the patient is a healthy-appearing 14-year-old boy whose height is below the third percentile and whose weight is at the 50th percentile. His bone age is determined to be 11 years. A laboratory workup, including thyroid stimulating hormone TSH, is unremarkable. What is the most likely diagnosis?? A: Constitutional growth delay, B: Familial short stature, C: Hypothyroidism, D: Celiac disease, E: Growth hormone deficiency,  <response>: Based on the information provided in the question stem, the key findings are:- 14-year-old boy whose height is below the 3rd percentile but weight is normal - Was growing at same rate as peers until past year- No evidence of delayed puberty in mother, fathers history unknown- Healthy appearing, no complaints- Bone age is 11 years - Normal thyroid functionThis suggests a normal variant growth pattern rather than an endocrine or gastrointestinal disorder.
