This patient most likely has constitutional growth delay.
Children with constitutional growth delay have a normal growth velocity. There will usually be a family history of delayed puberty in a parent or a sibling. Children will reach an appropriate final adult height that is within their genetic potential. This diagnosis can be made using history (including parental and siblings’ growth and pubertal history) and thorough physical examination. If performed, a bone age X-ray will be delayed compared to chronologic age.
