genetic alterations

Researchers have uncovered clearly recognizable genetic alterations in tumors and tissue removed from patients with early-stage lung cancers that look like good predictors of which of these cancers are more likely to recur.

Researchers at Johns Hopkins have discovered that two clinically different inherited syndromes are in fact variations of the same disorder.

The scientists suggest that at least for this class of disorders, the total number and "strength" of genetic alterations an individual carries throughout the genome can generate a range of symptoms wide enough to appear like different conditions.
