2023年6月8日 · PS4与PM2可以一起使用? 2015年的ACMG指南 指出: PS4: 变异位点在患病人群中的出现频率要 显著高于 对照人群(Fisher精确概率检验或卡方检验)。 注1:可选择使用相对风险值或者OR值来评估, 建议OR 大于 5.0 且置信区间不能包括1.0;
Overview of specifications to the ACMG/AMP variant …
The ACMG/AMP guidelines provides a method for this data type to still be utilized as PS4 evidence by noting “in instances of very rare variants where case–control studies may not reach statistical significance, the prior observation of the variant in multiple unrelated patients with the same phenotype, and its absence in controls, may be ...
Expert Specification of the ACMG/AMP Variant Interpretation …
The ACMG/AMP guidelines allow for the counting of probands as evidence for PS4 in the absence of case-control studies. For autosomal recessive HL, we recommend counting probands through PM3 (see below) where allelic data can be taken into account.

2018年1月4日 · The current ACMG/AMP framework assigns weight to increased prevalence of a variant in cases compared with controls (PS4), but does not provide guidance for combining separate studies reporting...
PS4 Calculator - cardiodb.org
This calculator can be used to calculate an odds ratio (OR) which can inform the application of the ACMG PS4 criterion for variants in genes related to autosomal dominant disorders. This calculator is not intended to be used in the context of autosomal recessive disorders.
• Implementation of ACMG/AMP guidelines has increased interpretation concordance between labs • >1/3 discrepancies due to differences in classification algorithms • Inconsistencies in application of ACMG/AMP criteria
Quantitative thresholds for variant enrichment in 13,845 cases ...
2023年12月18日 · The ACMG/AMP guidelines recommend assigning strong PS4 to variants with OR (or RR) > 5 and 95% CI of OR (or RR) > 1.0 in case–control comparisons. Our data indicate the recommended OR > 5 threshold is fairly precise, while OR > 6 is required to achieve strong evidence strength based on credibly classified variants.
VarSeq-VSClinical:ACMG(二) - 知乎专栏
ACMG 指南提供了两套标准:一套用于致病或可能致病变异体的分类,另一套用于良性或可能良性变异体的分类(第 3 章)。 每个致病性标准的权重分别为极强(PVS1)、强(PS1-4)、中等(PM1-6)或支持(PP1-5),每个良性标准的权重分别为独立(BA1)、强(BS1-4)或支持(BP1-6)。 对于给定的变异体,临床医生根据观察到的变异体证据选择标准。 然后,根据评分规则组合标准,从五级系统中选择最终分类。 该系统允许遗传学家根据其实验室或 ClinVar 等其 …
