Key result
Deep sequencing of myxoinflammatory fibroblastic sarcoma revealed that the recurrent t(1;10) translocation likely results in loss of genetic material from 1p and 10q rather than a functional fusion gene.
Why the study?
To investigate the molecular outcome of the t(1;10) translocation and the VGLL3 amplicon, and assess the spectrum of other recurrent genomic features in myxoinflammatory fibroblastic sarcoma.
Population
Myxoinflammatory fibroblastic sarcoma (MIFS) and MIFS-like tumors
Design
Genomic profiling study using WGS, Cap-seq, RNA-seq, and genomic arrays

Challenges fusion gene model in MIFS; leaves open whether 1p/10q loss or VGLL3 drives pathogenesis.
The recurrent t(1;10) translocation in MIFS likely results in loss of genetic material from 1p and 10q rather than forming functional fusion transcripts, while VGLL3 amplification is a consistent feature.
Arbajian et al. (2020) studied Myxoinflammatory fibroblastic sarcoma. Deep sequencing (WGS, Cap-seq, RNA-seq) was evaluated on Molecular outcome of the t(1;10) and the VGLL3 amplicon, and spectrum of other recurrent genomic features. Deep sequencing of myxoinflammatory fibroblastic sarcoma revealed that the recurrent t(1;10) translocation likely results in loss of genetic material from 1p and 10q rather than a functional fusion gene.
