  1. LOH = loss of heterozygosity.
  2. *Pancreatic adenocarcinoma samples for DNA preparation were macrodissected from a liver metastasis (Patient 3) and a lymph node metastasis (Patient 4).
  3. +Gene positions are with reference to the UCSC Genome Browser (GRCh37/hg19) assembly. Mutations are listed with the identified base change first, followed by the altered residue in the target protein. The mutations identified in our patients have been deposited in ClinVar (http://www.ncbi.nlm.nih.gov/clinvar/) on 28 January 2016 under Submission Record SUB1321610, Monnat Lab.
  4. COSMIC: YES = mutation is listed in the Catalog of Somatic Mutations in Cancer database, http://cancer.sanger.ac.uk/cosmic, with ‘multiple’ indicating the presence of several COSMIC records for this mutation, though often in different tumor types.
  5. §This needs to be further validated as this position is known to be artifact-prone.
  6. KIT p.M618I variant is a rare germline variant (3 examples listed in the ExAC browser) and probably a rare benign variant.
