question:
Context: Mutations in the solute carrier family 9, subfamily A member 6 (SLC9A6) gene, encoding the endosomal Na+/H+ exchanger 6 (NHE6) are associated with Christianson syndrome, a syndromic form of X-linked intellectual disability characterized by microcephaly, severe global developmental delay, autistic behavior, early onset seizures and ataxia. In a 7-year-old boy with characteristic clinical and neuroimaging features of Christianson syndrome and epileptic encephalopathy with continuous spikes and waves during sleep, we identified a novel splice site mutation (IVS10-1G>A) in SLC9A6. These findings expand the clinical spectrum of the syndrome and indicate NHE6 dysfunction as a new cause of electrical status epilepticus during slow-wave sleep (ESES). 
 Question: Mutation of which gene is implicated in the Christianson syndrome?
answer:
slc9a6


question:
Context: Protein ETHE1, mitochondrial , also known as ''ethylmalonic encephalopathy 1 protein'' and ''per sulfide dioxygenase'', is a protein that in humans is encoded by the ETHE1 gene located on chromosome 19. 
 Question: Which chromosome is the gene ETHE1 located on?
answer:
chromosome 19


question:
Context: While most teachers enjoy the summer break from work, other teachers try to find part-time work during that time. If you're one of those teachers who are finding part-time work during the summer, writing for children might be the right job you're looking for. During the school year, you're very familiar with children in your classroom. That means you know what children think about, how they talk and how they act. If you read stories and books for children with your students during the school year, you also know the kinds of story that children are fond of. As a teacher, you can go to the school library and find out what kinds of books students are most interested in. Also, what kinds of books seem to be in short supply? Use this information to create stories and novels. If you continue writing for children during the school year, you won't have enough time to write as much while you're teaching, but you can probably manage to work on at least one short story for children each month. Even if you don't finish these pieces during the school year, when school ends for the summer you will have lots of writing projects to finish and hand in to editors . Recently, many teachers have turned to writing for children as a part-time job. If you enjoy writing as much as you enjoy teaching, then writing for children might be the second job for you, too. 
 Question: Who is the passage probably written for?
answer:

teachers.
