Description

R. K. Rishabh and co-authors present a 2026 case report of a genetic overgrowth syndrome masquerading as acromegaly in a 33-year-old man. He stood nearly two metres tall with coarse facial features, an enlarged tongue, a jutting jaw, and extra nipples, a combination that pointed first to growth hormone excess.

Hormone testing ruled acromegaly out: his IGF-1 was actually low and growth hormone suppressed normally after glucose, while a tiny pituitary spot on MRI looked incidental. He also had mild intellectual disability and a similarly tall younger brother. Gene sequencing found a stop-making variant in GPC3, confirming Simpson-Golabi-Behmel syndrome, with his mother a carrier. The authors urge clinicians to consider overgrowth syndromes behind acromegaloid features.
