Targeted RNA-seq of FTLD-TDP brain samples

UNC13A features a cryptic exon which is expressed upon loss of nuclear TDP-43. Here, we perform targeted RNA-seq on RNA extracted from 10 FTLD-TDP brain samples, and four control samples, enriching for the cryptic exon via nested PCR. Each FTLD-TDP sample is heterozygous for rs12973192. There are two fastqs for each sample. One uses a sequence-specific reverse transcription primer, and detects both the cryptic-containing and correctly spliced isoforms. The second uses random hexamer primer (with specificity derived from downstream PCR and second strand synthesis) - this approach only detects the isoform containing the cryptic. The fastq files provided are demultiplexed and adaptor trimmed. Unique molecular identifiers have been moved to each read name, after "rbc:" (random barcode).
