Copy number variation (CNV) at several genomic loci has been associated with different human traits and diseases, but in many cases the findings could not be replicated. A new study provides insights into the degree of variation present at the amylase locus and calls into question a previous association between amylase copy number and body mass index.
基因组多个位置的拷贝数变异 (CNV) 与不同的人类特征和疾病有关,但在许多情况下,这些发现无法得到复制。一项新的研究提供了对淀粉酶基因座存在的变异程度的深入了解,并对淀粉酶拷贝数与体重指数之间的先前关联提出了质疑。
