Genes Involved and Proteins

Gene name
FGFR3 (Fibroblast Growth Factor Receptor 3)
Location
4p16.3
Protein description
115 kDa; contains, from N-term to C- term: an extracellular domain with a signal sequence and 3 Ig-like loops, a transmembrane domain, and an intracellular domain with 2 tyrosine kinase domains. FGFR3 is a fibroblast growth factor receptor with tyrosine kinase activity; binding of ligand (FGF) induces receptor dimerization, autophosphorylation and signal transduction
Gene name
ETV6 (ets variant 6)
Location
12p13.2
Protein description
53 and 57 kDa; contains, from N-term to C- term, an helix -loop-helix (HLH) domain (or"sterile alpha domain" SAM) responsible ofr dimerization, and a sequence specific DNA-binding domain (ETS domain); binds to 5 CCGGAAGT 3; ETV6 is a member of the ETS family of transcription factors; transcriptional repressor

Result of the Chromosomal Anomaly

Description

5 ETV6-3FGFR3; splicing variants (1618 and 1767 bp); the 1767 bp variant is an in frame fusion of ETV6 exon 5 to FGFR3 exon 10; both breakpoints are within exons; no reciprocal transcript.contains, from N-term to C- term, the HLH domain of ETV6 fused to the tyrosine kinase domains of FGFR3
