The present invention relates to methods of detecting region(s) of interest in a gene comprising a polyA tail. The region(s) of interest can include gene(s), region(s), mutation(s), deletion(s), insertion(s), indel(s), and/or translocation(s). The region(s) can be greater than or less than 1 kilobases from the polyA tail. Methods can include forming a library of single cell transcripts comprising the region(s) in close proximity to a cell barcode and a unique molecular identifier (UMI). Methods for distinguishing cells by genotype can include amplifying the transcripts using PCR methods and detecting the cell barcode and UMI using single cell sequencing methods. Transcripts can be enriched using tagged region-specific PCR primers. Cell barcodes can be brought into close proximity to the region(s) by circularizing the transcripts. Sequencing of the transcripts can include using primer binding sites added during PCR amplification and library indexes for multiplexed sequencing.

Single cell sequencing libraries of genomic transcript regions of interest in proximity to barcodes, and genotyping of said libraries

Embodiments disclosed herein provide methods for identifying cell-type-specific nucleosomal DNA modifications. The methods leverage nucleosomal DNA barcoding and pool-and-split multiplexing to provide high-throughout, quantitative profiling of nucleosomal DNA states. The methods enable the profiling of multiple nucleosomal DNA marks across different cell types and/or conditions thereby linking quantitative changes in chromatin landscapes to different genotypes and chemical and physical perturbations.
