In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Women with Turner syndrome (TS) have an increased prevalence of hearing loss, with conductive (CHL) and sensorineural (SNHL) components. The association between hearing loss and clinical parameters, particularly oestrogen and previous growth hormone (GH) treatment, was investigated.', 'A cross-sectional study of pure tone audiometry tests in an adult TS population. Previous ENT history, karyotype, anthropomorphic measurements and the impact of oestrogen and childhood GH therapy were assessed. One hundred and thirty-eight women (median age 29, range 16-67 years) completed the study.', 'Normal hearing was found in 20.3% of women, CHL in 18.8%, SNHL in 57.2% and confounding factors in 3.6%. Neither CHL nor SNHL were associated with oestrogen deficiency or GH treatment independent of age. CHL but not SNHL was more common in those with a history of recurrent otitis media (p < 0.01) and monosomy 45,X (p < 0.01).\Question: Are oestrogen deficiency and growth hormone treatment in childhood associated with hearing in adults with turner syndrome?
Example Output: Current regimens of oestrogen and GH therapy have no impact on adult hearing loss in TS, independent of age. The prevalence of SNHL increases with age. CHL but not SNHL is associated with ENT history and karyotype. According to present evidence, the only possible intervention to reduce hearing loss in women with TS remains assiduous treatment of ENT problems in childhood.

Example Input: Context: The yeast cell cycle is largely controlled by the cyclin-dependent kinase (CDK) Cdc28. Recent evidence suggests that both CDK complex stability as well as function during mitosis is determined by precise regulation of Swe1, a CDK inhibitory kinase and cyclin binding partner. A model of mitotic progression has been provided by study of filamentous yeast. When facing nutrient-limited conditions, Ras2-mediated PKA and MAPK signaling cascades induce a switch from round to filamentous morphology resulting in delayed mitotic progression.', 'To delineate how the dimorphic switch contributes to cell cycle regulation, temperature sensitive cdc28 mutants exhibiting constitutive filamentation were subjected to epistasis analyses with RAS2 signaling effectors. It was found that Swe1-mediated inhibitory tyrosine phosphorylation of Cdc28 during filamentous growth is in part mediated by Ras2 activation of PKA, but not Kss1-MAPK, signaling. This pathway is further influenced by Cks1, a conserved CDK-binding partner of elusive function with multiple proposed roles in CDK activation, transcriptional regulation and ubiquitin-mediated proteasome degradation.\Question: Do morphogenesis signaling components influence cell cycle regulation by cyclin dependent kinase?
Example Output: The dynamic balance between Cks1- and Swe1-dependent regulation of Cdc28 and, thereby, the timing of mitosis during yeast dimorphism is regulated in part by Ras2/cAMP-mediated PKA signaling, a key pathway controlling filamentous growth.

Example Input: Context: Several association studies confirmed high-mobility group-A2 gene (HMGA2) polymorphisms as the most relevant variants contributing to height variability. Animal models and deletions in humans suggest that alterations of HMGA2 might be relevant in causing short stature. Together, these observations led us to investigate the involvement of HMGA2 in idiopathic short stature (ISS) through an association study and a mutation screening.', 'We conducted an association study (155 ISS patients and 318 normal stature controls) with three HMGA2 single-nucleotide polymorphisms (SNPs) (SNPs rs1042725, rs7968682, and rs7968902) using a TaqMan-based assay. The patients were then analyzed by direct sequencing and multiplex ligation-dependent probe amplification (MLPA) to detect point mutations and genomic micro-rearrangements.', 'Considering a recessive model, an OR value >1 was observed for genotypes rs7968682 TT (Odds ratio (OR) = 1.72, confidence interval (CI): 1.14-2.58) and rs1042725 TT (OR = 1.51, CI: 1.00-2.28) in accordance to the effect exhibited by the single alleles in the general population. None of the patients carried possibly causative HMGA2 mutations.\Question: Are variations in the high-mobility group-A2 gene ( HMGA2 ) associated with idiopathic short stature?
Example Output:
Besides the already known role in determining variability in human height, HMGA2 polymorphisms also contribute to susceptibility to ISS. Moreover, we here report the first mutation screening performed in ISS concluding that HMGA2 has not a significant impact on the monogenic form of ISS.
