Genes Involved and Proteins

Gene name
PDGFRB (platelet-derived growth factor receptor, beta polypeptide)
Location
5q32
Protein description
contains from N-term to C-term: a ligand binding domain, a transmembrane domain, and a Tyrosine kinase domain; PDGFRB is the receptor for PDGFB (platelet-derived growth factor-b); membrane protein; belongs to the immunoglobulin superfamily
Gene name
HIP1 (Huntingtin interactin protein 1)
Location
7q11.23
Protein description
contains a leucine zipper and, in C-term, a region with homology to a protein of the cytoskeleton; membrane associated protein.

Result of the Chromosomal Anomaly

Description

5 HIP1- 3 PDGFRb; breakpoint in PDGFRb similar to what is found in the t(5;12)(q33;p12)180 kDa; contained nearly all of the HIP1 coding sequence, including the leucine zipper and talin homology domains, fused in frame to the transmembrane and tyrosine kinase domain of the PDGFb; the reciprocal PDGFb-HIP1 transcript is not expressed

Oncogenesis

constitutive activation of PDGFb (by tyrosine autophosphorylation).
