Q: Context: Leonard (Phoenix) is walking along a bridge over a creek in Brooklyn, when suddenly he jumps into the water in an attempted suicide. He changes his mind and quickly walks home to his parents' apartment. His mother, seeing him dripping wet, tells her husband their son has tried it again and it becomes evident that Leonard has tried to kill himself before. His parents tell him that a potential business partner and his family are invited for dinner that night and ask him to be present. When they arrive, Leonard finds that he had been set up with the other family's daughter, Sandra (Shaw). She inquires about his interest in photography and notices a photo of a girl above his headboard. He explains he had been engaged to the girl for several years, but the relationship was broken off when it turned out both he and his fiancee carried the gene for TaySachs disease, which results in diseased children who generally don't live beyond age 12, so they would be unable to have healthy children. Leonard meets a new neighbor, Michelle (Paltrow), and is immediately attracted to her, choosing to ignore that she has a drug usage problem. He learns that she is dating a married partner in her law firm, Ronald (Koteas). At her request, Leonard agrees to meet Ronald and Michelle for dinner at a restaurant. The couple leave him later that evening, as they have plans to attend the Metropolitan Opera. Leonard returns home upset, but to his surprise, Sandra arrives, sent over by Leonard's parents. She is under the impression that Leonard wanted her to come by, but realizes by his surprised look, that she was set up. She apologizes for the misunderstanding and says that if he isn't interested, a lot of other guys are. Leonard says that he likes her, and they kiss and eventually make love, and with time, his relationship with Sandra deepens. Michelle calls Leonard and says she is sick. He takes her to the hospital, where she has a D&C for a miscarriage. She had not known she was pregnant and is even more upset that Ronald didn't respond to her calls. Leonard takes her home but Ronald arrives. Leonard hides while Ronald apologizes to Michelle for not having come to her aid. Michelle coldly asks Ronald to leave. She then asks Leonard to write something on her forearm with his finger while she falls asleep. Leonard writes "I love you". Two weeks later, Michelle meets Leonard on the roof of their building and tells him that she has broken up with Ronald and is going to San Francisco. Leonard tells her not to leave and professes his love for her. They have sex and plan to leave together the next day for San Francisco. On New Year's Eve, Leonard buys an engagement ring for Michelle. He is then summoned by Sandra's father and is offered a partnership in the family businesses, with the assumption that he is going to marry Sandra. Noticing the jeweler's gift bag Leonard is holding, the father assumes it is for Sandra; Leonard lies that it is. During his parents' New Year's Eve party, Leonard ducks out to the courtyard to meet Michelle. Michelle arrives ten minutes past departure time and tells Leonard that she isn't going to San Francisco, because Ronald, having learned Michelle is leaving him for California, decided to leave his wife and children for her. Distraught, Leonard breaks things off with her for good. Feeling desolate, Leonard heads to the beach, presumably intending to kill himself. When he drops a glove that Sandra had bought for him, he realizes that, in Sandra, he has found someone who loves him and with whom he can build a decent life. He picks up the glove and sees the boxed engagement ring lying on the sand, where he had thrown it from the boardwalk earlier. He returns to the party, where he gives Sandra the ring and embraces her in a prolonged hug. 
 Question: where Leonard meets Ronald and Michelle for dinner in this movie?

A: a restaurant

Q: Context: Mutations in LYST, a gene encoding a putative lysosomal trafficking protein, cause Chediak-Higashi syndrome (CHS), an autosomal recessive disorder typically characterized by infantile-onset hemophagocytic syndrome and immunodeficiency, and oculocutaneous albinism. A small number of reports of rare, attenuated forms of CHS exist, with affected individuals exhibiting progressive neurodegenerative disease beginning in early adulthood with cognitive decline, parkinsonism, features of spinocerebellar degeneration, and peripheral neuropathy, as well as subtle pigmentary abnormalities and subclinical or absent immune dysfunction. In a consanguineous Pakistani kindred with clinical phenotypes consistent with attenuated CHS, we performed SNP array-based homozygosity mapping and whole gene sequencing of LYST. We identified three individuals homozygous for a novel six base pair in-frame deletion in LYST (c.9827_9832ATACAA), predicting the loss of asparagine and threonine residues from the LYST transcript (p.Asn3276_Thr3277del), and segregating with the phenotype in this family. We further characterize the neurologic features of the attenuated form of CHS, and discuss pathophysiologic mechanisms underlying the neurodegenerative components of CHS. Attenuated CHS is phenotypically heterogenous and should be considered when young adults develop neurodegenerative disease and have pigmentary abnormalities. We briefly discuss surveillance and management of patients with CHS-related neurodegeneration. 
 Question: Which mutated gene causes the ChediakHigashi Syndrome?

A:
lysosomal trafficking regulator gene
