PDGFRA Mutation Analysis
Alternative name:
PDGFR Alpha Mutation Analysis
Methodology
Molecular
Test Description and clinical significance
Genes
PDGFRA (eg, exons 12, 18)
Disease:
Idiopathic hypereosinophilic syndrome, Somatic and Familial GIST, dermatofibrosarcoma protuberans, lung adenocarcinoma, glioblastoma multiforme, colon adenocarcinoma, and cutaneous melanoma
Molecular test that utilizes NGS technology to detect mutations in PDGFRA. Mutations in this gene have been associated with idiopathic hypereosinophilic syndrome, somatic and familial gastrointestinal stromal tumors, and a variety of other cancers.
Specimen Requirements
Collection:
FFPE sections, 5-10 sections are recommended at 4 to 10 micron. A minimum of 20 ?l of each DNA with a concentration of at least 5ng/?l and an OD260/280 ratio of 1.7-1.9 and 2.0-2.1 respectively, obtained on a spectrophotometer is required.
Stability:
FFPE blocks- Indefinitely/ FFPE Slides-4 weeks
Unacceptable Conditions:
Specimen submitted is in the incorrect fixative. Insufficient specimen (less than 10% of tumor). Unlabeled or improperly labeled specimens. Decalcified specimens. Improperly stored DNA or RNA.
Storage & Transport
Store FFPE blocks and slides at room temperature. Genomic DNA must be stored at 2–8°C for several weeks post extraction, then at –15 to –25°C for long term storage
