ParSE-seq: a calibrated multiplexed assay to facilitate the clinical classification of putative splice-altering variants.

Interpreting the clinical significance of putative splice-altering variants outside canonical splice sites remains difficult without time-intensive experimental studies. To address this, we introduce Parallel Splice Effect Sequencing (ParSE-seq), a multiplexed assay to quantify variant effects on RNA splicing. We first apply this technique to study hundreds of variants in the arrhythmia-associated gene SCN5A.

High-throughput functional mapping of variants in an arrhythmia gene, KCNE1, reveals novel biology.

Background: KCNE1 encodes a 129-residue cardiac potassium channel (I) subunit. KCNE1 variants are associated with long QT syndrome and atrial fibrillation. However, most variants have insufficient evidence of clinical consequences and thus limited clinical utility.
