Summary
Researchers identified a novel synovial sarcoma (SS) fusion variant with a small deletion. This discovery offers new insights into the oncogenic role of SSX genes in this rare cancer.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- Synovial sarcoma (SS) is a rare soft tissue sarcoma.
- Over 95% of SS cases exhibit the t(X;18)(p11.2;q11.2) chromosomal translocation.
- This translocation results in fusion genes involving SYT and SSX genes.
Observation:
- The most common fusion subtypes are SYT4-SSX1, SYT4-SSX2, and SYT4-SSX4.
- Variant fusion transcripts, often due to insertions, are less common.
- A novel fusion transcript with a small deletion was identified.
Findings:
- The novel fusion transcript involves a deletion in the SSX gene portion.
- This deletion leads to an alternative reading frame in the SSX component.
- This represents a new type of SS fusion variant.
Implications:
- The identified fusion variant may alter the function of the SSX protein.
- Understanding this variant can provide deeper insights into SS pathogenesis.
- This finding could potentially inform future diagnostic or therapeutic strategies for synovial sarcoma.

01:32RNA Splicing
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

02:18Alternative RNA Splicing
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
