Q: Given a passage with a context and an answer, 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.
Context: Mutations of the caspase-activating recruitment domain 15 (CARD15) gene on chromosome 16 are associated with chronic inflammatory granulomatous bowel disease (Crohn's disease). Sarcoidosis is a systemic granulomatous disease with unknown etiology, which shares histological features with Crohn's disease.", 'To evaluate whether ethnic Danes with sarcoidosis have an increased frequency of CARD15 mutations compared to healthy control subjects.', 'Genotyping for CARD15 mutations R702W, G908R, and L1007fsinsC, also designated single nucleotide polymorphism (SNP) SNP8, SNP12 and SNP13, respectively, were performed by capillary electrophoresis single-strand confirmation polymorphism in 53 patients with histologically verified sarcoidosis and in 103 healthy controls.', 'The frequencies of CARD15 mutations in sarcoidosis patients were: SNP8, 4/106 chromosomes (3.8%); SNP12, 2/106 chromosomes (1.9%); SNP13, 2/106 chromosomes (1.9%); SNP8+SNP12+SNP13, 8/106 chromosomes (7.6%). All 8 patients were heterozygous. The frequencies in controls were: SNP8, 9/206 chromosomes (4.4%); SNP12, 2/206 chromosomes (1.0%); SNP13, 4/206 chromosomes (1.9%); SNP8+SNP12+SNP13, 15/206 chromosomes (7.3%). All controls were heterozygous. The differences were not statistically significant (p>0.05). Furthermore, the course of disease was not significantly different in the 8 patients with CARD15 mutations and the 45 patients without mutations.
Answer: The frequency of CARD15 mutations is not increased in ethnic Danish patients with sarcoidosis, and heterozygosity for such mutations apparently has no influence on the course of disease.
A:
Are cARD15 single nucleotide polymorphisms 8 , 12 and 13 increased in ethnic Danes with sarcoidosis?
