Summary
Researchers identified 57 population-specific chimeric RNAs, including SUZ12P1-CRLF3, which can help find gene fusions in normal tissues. This approach aids in discovering hard-to-find structural variants.
Area of Science:
- Genomics
- Molecular Biology
- Population Genetics
Background:
- Gene fusions are cancer hallmarks, but chimeric transcripts also occur in normal tissues.
- Identifying structural variations producing these transcripts in the general population is challenging.
Approach:
- Developed a method to target population-specific chimeric RNAs from gene fusions.
- Analyzed the GTEx cohort to identify 57 chimeric RNAs, including SUZ12P1-CRLF3 and TFG-ADGRG7.
- Assessed the distribution of SUZ12P1-CRLF3 across populations using the 1000 Genomes Project data.
Key Points:
- Discovered 57 polymorphic chimeric RNAs.
- Characterized the SUZ12P1-CRLF3 chimeric RNA and its associated rearrangement.
- Established a novel bottom-up strategy for identifying structural variants that yield transcribed gene fusions.
Conclusions:
- SUZ12P1-CRLF3 arises from a common structural variant in African populations, with a defined formation mechanism.
- Found an association between the SUZ12P1-CRLF3 variant and indications of Neurofibromatosis Type I.
- Demonstrated a new approach for detecting rare, functional structural variants via population-specific fusion transcripts.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
