You will be given a definition of a task first, then some input of the task.
Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

We investigated the association of KLOTHO gene single nucleotide polymorphisms (SNPs) with various laboratory data in 476 Japanese healthy subjects.', 'The genotyping of G-395A in the promoter region and C1818T in exon 4 was performed using PCR with confronting 2-pair primers assay.', 'Multivariate analysis adjusted for age demonstrated that in men, body-fat ratio was high, and HDL cholesterol level was low in A allele carriers of G-395A compared with GG. In women, glucose was high in A allele carriers of G-395A compared with GG, and also in T allele carriers of C1818T compared with CC. When divided into 2 groups according to age, in men <60 y, body mass index, body-fat ratio and waist circumference were high in A carriers of G-395A compared with GG. In women <60 y, bone mineral density was high in A allele carriers of G-395A compared with GG, and systolic blood pressure and glucose were high in T carriers of C1818T compared with CC.
Output:
Are kLOTHO gene polymorphisms G-395A and C1818T associated with lipid and glucose metabolism , bone mineral density and systolic blood pressure in Japanese healthy subjects?
