Doctors halt growth of seven-foot boy

Because of a unique genetic anomaly, Brenden Adams is so lofty that he has to stoop to get through doorways, barely fits in his mother's car and dangles uncomfortably over normal sized beds.

Doctors who spent years puzzling over the cause of his runaway growth have now succeeded in slowing its pace, declaring Brenden the only known case of his kind in the world.

"We were concerned that he would continue growing and there'd just be no stopping it," said Dr Melissa Parisi, a geneticist at Seattle Children's Hospital, who has been seeing Brenden since he was four years old.
