Example Input: Restless legs syndrome (RLS), also known as Willis-Ekbom disease, is a sensory-motor neurological disorder with a circadian component. RLS is characterized by uncomfortable sensations in the extremities, generally at night or during sleep, which often leads to an uncontrollable urge to move them for relief. Recently, genomic studies identified single-nucleotide polymorphisms in BTBD9, along with three other genes, as being associated with a higher risk of RLS. Little is known about the function of BTBD9 or its potential role in the pathophysiology of RLS. We therefore examined a line of Btbd9 mutant mice we recently generated for phenotypes similar to symptoms found in RLS patients. We observed that the Btbd9 mutant mice had motor restlessness, sensory alterations likely limited to the rest phase, and decreased sleep and increased wake times during the rest phase. Additionally, the Btbd9 mutant mice had altered serum iron levels and monoamine neurotransmitter systems. Furthermore, the sensory alterations in the Btbd9 mutant mice were relieved using ropinirole, a dopaminergic agonist widely used for RLS treatment. These results, taken together, suggest that the Btbd9 mutant mice model several characteristics similar to RLS and would therefore be the first genotypic mouse model of RLS. Furthermore, our data provide further evidence that BTBD9 is involved in RLS, and future studies of the Btbd9 mutant mice will help shine light on its role in the pathophysiology of RLS. Finally, our data argue for the utility of Btbd9 mutant mice to discover and screen novel therapeutics for RLS.
Example Output: Willis-Ekbom disease is also known as?

Example Input: Coming off their Monday night road win over the Saints, the Vikings went home for a Week 6 NFC North duel with the Detroit Lions. In the first quarter, the Vikes got an early lead as Lions QB Dan Orlovsky unintentionally ran out of the back of his own end zone, giving Minnesota a safety which Orlovsky didn't know why the whistles were blown. In the second quarter, Detroit got the lead as kicker Jason Hanson got a 40-yard field goal. In the third quarter, the Lions increased their lead as Orlovsky completed a 12-yard TD pass to WR Calvin Johnson. The Vikings answered with QB Gus Frerotte completing an 86-yard TD pass to WR Bernard Berrian. In the end of the fourth quarter, the Vikes got in field goal range due to a controversial pass interference call on Leigh Bodden. The Vikes sealed the win with kicker Ryan Longwell nailing the game-winning 26-yard field goal.
Example Output:
Which QB threw the longest TD pass?
