Automated design of hammerhead ribozymes and validation by targeting the PABPN1 gene transcript.

abstract：:The majority of genome-wide association study (GWAS) risk variants reside in non-coding DNA sequences. Understanding how these sequence modifications lead to transcriptional alterations and cell-to-cell variability can help unraveling genotype-phenotype relationships. Here, we describe a computational method, dubbed C...
