概括

心脏病学中的基因测试往往会破坏诊断,不是因为临床医生的错误,而是因为遗传知识的差距. 这导致了医疗不可知症,阻碍了有效的患者护理和诊断.

科学领域:

医学遗传学医学遗传学
心脏病学心脏病学
诊断的社会学诊断的社会学

背景情况:

遗传检测在心脏病学中未得到充分利用,这通常归因于临床医生缺乏遗传素养.
很少有研究探讨了临床医生承担的复杂解释过程,以将遗传测试结果转化为可行的临床决策.

研究的目的:

调查心脏病学家在将遗传检测结果整合到诊断推理中时执行的解释性工作.
了解遗传测试结果,无论类型 (阳性,阴性,VUS),如何影响心脏病学家的诊断过程和决策.

主要方法:

定性研究涉及对29名心脏病专家进行深入采访.
对心脏病学家的经验进行分析,将遗传发现与患者特定的临床数据 (症状,病史,家族病史) 相协调.

主要成果:

基因检测,虽然可能提供分子确认,但经常扰乱了心脏病学家的诊断推断过程.
干扰源于将遗传结果与全面的患者信息相协调,而不是遗传结果本身的性质.
心脏病学家试图通过将遗传检测结果排除在外或修复来解决这些干扰,但在使它们完全可行的方面取得了有限的成功.

结论:

遗传检测在心脏病学中的有限吸收和临床效用不仅仅是由于个体临床医生的遗传素养.
存在一个集体挑战:基础遗传知识基础上的差距有助于医学预后,其特点是无法理解患者的症状和不确定性,而不是确定的诊断.

Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
