His team has recently reported that melanoma and lung cancer patients with more neoantigen -
coding tumor mutations are more likely to respond to immune checkpoint blockers.

The team integrated three, complementary gene sequencing approaches to look for
mutations in
tumor cells from SS patients: whole - genome sequencing in six subjects, sequencing of all protein -
coding regions (exomes) in 66 subjects, and comparing variation in the number of copies of all genes across the genome in 80 subjects.
But the diagnostic test, which checks to see if a patient's
tumor carries a
mutation in a gene
coding for anaplastic lymphoma kinase, called ALK, is just $ 250.
Researchers from the University of Chicago and the Beijing Institute of Genomics estimate that the
tumor, about 3.5 centimeters in diameter, contained more than 100 million distinct
mutations within the
coding regions of its genes — thousands of times more than expected.
We observed an average of 14.5 «tier 1» (
coding)
mutations per
tumor in the 24 WGS cases; on average, ~ 3 of these affected recurrently mutated genes in M1
tumors, and ~ 2 affected recurrently mutated genes in M3
tumors.
We find any
mutations in the
tumor that are not in the germline, and identify which of those are novel, protein -
coding variants.
Variations in the genetic
code, from single point
mutations to large structural or copy number alterations, influence susceptibility, onset, and progression of genetic diseases and
tumor transformation.
