Genes involved and Proteins

Gene NameFGFR1 (Fibroblast Growth Factor Receptor 1)
Location 8p11.23
Protein FGF receptor; membrane associated tyrosine kinase. Signal transduction.
Gene NameERVK-6 (endogenous retrovirus group K member 6, envelope)
Location 7p22.1
Note ERVK/HERV-K are dissemninated throughout the whole genome; one of these, located in 19q13, was found implicated in the t(8;19)
Protein ERV/HERV sequences are thousands of endogenous retroviruses. Most -if not all- are defective, containing deletions or nonsense mutations. The ERVK/HERV-K family is the most recently inserted family, after chimpanzees and men diverged. ERV element consists of two identical, nontranslated long terminal repeats (LTRs) flanking an internal region that encodes proteins required for viral replication and assembly. Defective ERV have lost their internal region and LTRs often remain solos. These retroelements (RE) could be agents of genomic instability. They can cause host DNA rearrangements due to recombination events, by transduction of RE flanking sequences into new genomic loci, by creating pseudogenes, or by causing RNA recombination.
The HERV-K subgroup have been suspected to be involved in cancer (including seminomas), autoimmune diseases, and neuronal diseases such as schizophrenia.

Result of the chromosomal anomaly

Hybrid gene
Description 5' sequences from an ERV element - 3' FGFR1 (starting at exon 9)
Fusion Protein
Description Open reading frame from ERV sequences fused to part of the juxtamembrane domain and the tyrosine kinase-encoding regions of the FGFR1 gene.
