DUCKS4: a comprehensive workflow for Nanopore sequencing analysis of facioscapulohumeral muscular dystrophy (FSHD).
Article in Human genomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
motivationFacioscapulohumeral Muscular Dystrophy (FSHD) is an autosomal dominant form of muscular dystrophy caused by genetic or epigenetic changes within the D4Z4-repeat at the DUX4-gene, on chromosome 4q. Genetic analysis is challenging due to a nearly identical region on chromosome 10, multiple haplotypes, long and short repeat subtypes, and complex rearrangements such as translocations and duplications. So far, no single method detects all known causes of FSHD.
resultsWe have developed an integrated approach combining an optimized wet-lab protocol with an automated bioinformatics workflow, called DUCKS4. It enables read-level resolution of the D4Z4 array for FSHD1 repeat sizing, variant detection for FSHD2, and detection of methylation patterns. Using NCBI BLAST, it assigns reads to chromosomes and haplotypes, supporting robust filtering and analysis. Our approach also includes a novel adaptive sampling workflow for human high molecular-weight DNA. With long-read Nanopore sequencing technology, our tool enables precise determination of D4Z4 array size, individual haplotype assignment, methylation profiling, and complex allele analysis. It also allows for the detection of mosaicism and structural variation like interchromosomal translocations, providing a comprehensive, single-method solution for FSHD analysis. AVAILABILITY AND IMPLEMENTATION: DUCKS4 is implemented within a Docker environment.
