在糖尿病研究中，外显子组测序带来了诊断方面的挑战，因为根据出现频率、功能影响以及基因组和环境背景的不同，HNF1A基因变异可能导致青少年成人发病型糖尿病（MODY）、增加2型糖尿病风险，或者属于良性变异。准确诊断至关重要，因为这关系到治疗方案、疾病进展以及家族患病风险。我们描述了一个多维功能数据集，该数据集包含在12940名个体外显子组中鉴定出的73个HNF1A错义变异。我们的目标是开发一个分析框架，以便在HNF1A表型连续体上对变异进行分层，从而助力诊断解读。HNF1A变异的功能通过四种不同的分子检测方法来确定。利用主成分分析、K均值聚类和层次聚类来探究多维数据集的结构。整合了组织特异性异构体表达和功能域的权重。功能注释的变异亚组被用于重新评估国家MODY诊断登记处的遗传诊断。HNF1A变异在各项检测中表现出一系列不同的特性。多参数数据的结构主要由转录激活作用塑造。通过无监督学习方法，我们获得了变异的高分辨率功能簇，这些功能簇将已知的导致MODY的致病性变异与良性变异以及2型糖尿病风险变异区分开来，进而分别对英国和挪威MODY诊断登记处鉴定出的4%和9%的HNF1A变异进行了重新分类。我们的原理验证分析有助于在连续体上对HNF1A变异进行有意义的分层，从而能够在糖尿病临床中更好地评估临床意义、管理和精准医疗。转录活性似乎是一种更优的读数，支持采用以转录激活为核心的实验设计进行高通量功能筛选。
Exome sequencing in diabetes presents a diagnostic challenge because depending on frequency, functional impact, and genomic and environmental contexts, HNF1A variants can cause maturity-onset diabetes of the young (MODY), increase type 2 diabetes risk, or be benign. A correct diagnosis matters as it informs on treatment, progression, and family risk. We describe a multi-dimensional functional dataset of 73 HNF1A missense variants identified in exomes of 12,940 individuals. Our aim was to develop an analytical framework for stratifying variants along the HNF1A phenotypic continuum to facilitate diagnostic interpretation. HNF1A variant function was determined by four different molecular assays. Structure of the multi-dimensional dataset was explored using principal component analysis, k-means, and hierarchical clustering. Weights for tissue-specific isoform expression and functional domain were integrated. Functionally annotated variant subgroups were used to re-evaluate genetic diagnoses in national MODY diagnostic registries. HNF1A variants demonstrated a range of behaviors across the assays. The structure of the multi-parametric data was shaped primarily by transactivation. Using unsupervised learning methods, we obtained high-resolution functional clusters of the variants that separated known causal MODY variants from benign and type 2 diabetes risk variants and led to reclassification of 4% and 9% of HNF1A variants identified in the UK and Norway MODY diagnostic registries, respectively. Our proof-of-principle analyses facilitated informative stratification of HNF1A variants along the continuum, allowing improved evaluation of clinical significance, management, and precision medicine in diabetes clinics. Transcriptional activity appears a superior readout supporting pursuit of transactivation-centric experimental designs for high-throughput functional screens.
