The annotation of GBA1 has been concealed by its protein-coding pseudogene GBAP1

Abstract excerpt

Mutations in GBA1 cause Gaucher disease and are the most important genetic risk factor for Parkinson’s disease. However, analysis of transcription at this locus is complicated by its highly homologous pseudogene, GBAP1 . We show that >50% of short RNA-sequencing reads mapping to GBA1 also map to GBAP1 . Thus, we used long-read RNA sequencing in the human brain, which allowed us to accurately quantify expression...
