By studying rare «copy number variations,» which are individual errant insertions or deletions of DNA segments (each of which occur in less than one percent of the population), researchers discovered a

The pivotal molecular markers that define the three tumor
clusters — mutational status of the IDH1 and IDH2
genes and loss of chromosome arms 1p and 19q — are already routinely checked in clinical care, Verhaak noted, so implementing the

In their
new study, the researchers looked for
gene clusters associated with calcium - binding motifs similar to those in known antibiotics such as daptomycin and friulimicin, which require calcium for their antimicrobial action.
