CNV最终的致病性等级与之前的一致,共分为五个等级,分别从五个维度对可能支持的证据进行分类。 与之前SNP/InDel 变异证据评估过程相似,我们需要首先定义CNV变异的支持证据,通过支持证据的打分来判断CNV的致病性等级,与之前不同按不同证据的个数相加的方法不同,CNV的等级是由每个符合的支持证据的得分相加而得到。最终得...
对于致病性判断,从2011年的ACMG的CNV解读指南的致病、意义未明、良性,调整为与单基因病的变异解读类似的5档:分值≥0.99分是致病 (P)、0.9≦分值≦0.98是可能致病 (LP)、分值≦-0.99是良性 (B)、-0.98≦分值≦-0.90是可能良性 (LB)、其他分值都是...

其中一个GenedX海报会议包括一些数据,这些数据表明外显子组测序能够检测出低于染色体微阵列(CMA)报告阈值的小拷贝数变异(CNV),以及CNV的检测结果与CMA一致性接近99%。这些发现表明,通过改进管道和平台,提高了数据质量。再加上与CMA相比,它能够识别许多其他类型的变异,并且其诊断产量提高了近三倍,1,2,3这些发现表明了...

Deletion/duplications (del/dup):copy number variants (also known as deletions/duplications, or del/dup for short) are detected using Fulgent’s sophisticated bioinformatic algorithm, CNVexonTM. Pathogenic variants found by this method are confirmed by Sanger sequencing, MLPA, or quantitative PCR (qPC...
