Disease relevance of PDGFRA


Psychiatry related information on PDGFRA

  • Using DNA of a patient with piebaldism, mental retardation, and multiple congenital anomalies associated with a 46,XY,del(4) (q12q21.1) karyotype, we carried out quantitative Southern blot hybridization analyses of the KIT gene and the adjacent PDGFRA (platelet-derived growth factor receptor alpha subunit) genes [5].

High impact information on PDGFRA


Chemical compound and disease context of PDGFRA


Biological context of PDGFRA

  • A bedside-to-benchtop translational research effort led to the identification of a constitutively activated fusion tyrosine kinase on chromosome 4q12, derived from an interstitial deletion, that fuses the platelet-derived growth factor receptor-alpha gene (PDGFRA) to an uncharacterized human gene FIP1-like-1 (FIP1L1) [14].
  • Furthermore, approximately 40% of responding patients lack the FIP1L1-PDGFRA fusion, suggesting genetic heterogeneity [14].
  • Mutational analysis of exons 9, 11, 13, and 17 of KIT, and exons 12 and 18 of PDGFRA was performed in all cases by denaturing high-pressure liquid chromatography (DHPLC) pre-screening, followed by direct sequencing [15].
  • However, although the incidence of MPD involving translocations of PDGFRB has been well established, to our knowledge there are only two previous reports describing a BCR-PDGFRA fusion gene, in 3 patients diagnosed with atypical CML [16].
  • Here, we report the molecular and cytogenetic characterization of a patient with BCR-PDGFRA-positive MPD who had a complete hematologic response after treatment with imatinib mesylate [16].

Anatomical context of PDGFRA


Associations of PDGFRA with chemical compounds

  • Treatment with low-dose imatinib (100 mg/d) produced complete and durable responses in all 8 FIP1L1-PDGFRA(+) cases treated [1].
  • Three tumours harboured PDGFRA exon 18 activating mutations; two were Asp --> Val(842) missense substitutions and one was a DIM842-844 amino acid deletion [15].
  • These rare neoplasms are remarkably sensitive to the KIT and PDGFRA kinase inhibitors imatinib (also known as Gleevec) and sunitinib (Sutent), which have recently been approved as the standard therapeutic courses for patients with inoperable GIST [8].
  • We detected a germline PDGFRA missense mutation, 2675G > T, resulting in a tyrosine substitution for the highly conserved aspartic acid at codon 846 [18].
  • Alternately, the mutant kinase proteins can be targeted using HSP90 inhibitors, which result in degradation of activated KIT and/or PDGFRA, or using KIT transcriptional repressors, such as flavopiridol [8].
  • This study is the largest reported to date on patients with advanced PDGFRA-mutant GISTs treated with imatinib [19].

Physical interactions of PDGFRA

  • All three matrices have been shown to purify a 90-kDa protein that is recognized by mAbs specific for the PDGF-R alpha extracellular domain. sPDGF-R alpha is capable of binding PDGF ligand in solution and can compete with cell-associated PDGF receptors for ligand binding [20].

Regulatory relationships of PDGFRA

  • This case likely represents an example of GIST with PDGFRA activating mutation and PDGFRA immunoreactivity without CD117 positivity, which has not been documented in the literature [21].
  • In addition, PDGF-BB, in the presence of anti-PDGF-R beta, bound only to PDGF-R alpha and caused suppression of SMC migration induced by fibronectin [22].
  • The TGF-beta 1-induced down-regulation of the PDGF-R alpha gene was rapid (maximal suppression by 2 h post-treatment) and preceded the decrease in cell-surface alpha-receptor (maximal reduction by 6 h post-treatment) [23].
  • AF tumors expressed minimal to null levels of KIT and PDGFRA but expressed levels of PDGFRB that are comparable with normal fibroblasts [24].
  • Intestinal Neurofibromatosis Is a Subtype of Familial GIST and Results From a Dominant Activating Mutation in PDGFRA [25].

Other interactions of PDGFRA

  • This review examines the current state of knowledge of HES and CEL and the implications of the FIP1L1-PDGFRA discovery on their diagnosis, classification, and management [14].
  • No mutations were detected with denaturing high-performance liquid chromatography in KIT exons 9, 11, 13 or 17, PDGFRA exons 12 and 18, or EGFR exons 18, 19 or 21 [4].
  • In summary, PDGFRA, PDGF and KIT dysregulation as well as growth inhibition of cell culture S462 by imatinib may suggest that MPNST patients benefit from treatment with imatinib [10].
  • Point mutations of c-kit gene or PDGFRA gene were identified only in three (8%) and two (6%) tumors, respectively [26].
  • This article describes the results of comprehensive molecular/biochemical analyses of the three receptors targeted by the drug (PDGFRB, PDGFRA, and KIT) in a series of 31 chordoma patients [27].
