Brenden Adams
Brenden Adams (born September 20, 1995 in Ellensburg, Washington) is an American who previously held the record for being the tallest teenager in the world. His father, Willie Adams, and mother, Debbie Ezell, first observed his extreme height condition when he was two months old. The condition is caused by an inversion in the 12th chromosome.
His activities included joining his middle school football team. In 2008, there was an attempt to halt Brenden's growth when he was 7:ft 4.5:in (2.248:m) tall.
Adams' growth curve almost mimics that of Robert Wadlow, the tallest man in recorded history. Some doctors estimate that Adams would have been over 8 feet (2.4:m) tall if he had kept growing constantly. After endocrinologist Dr. Gad Kletter's treatment with high-dose testosterone, his growth was arrested.
Adams was surp*ed by Broc Brown (born in 1997) in 2015 at 7'8" tall.
