gene variant

(MedPage Today) -- A gene called PYHIN1 may account for a surprisingly large proportion of asthma risk in people of African descent, said researchers conducting a meta-analysis of genome-wide association studies.

Patients with certain gene variant may have an increased risk of severe asthma attacks when exposed to fungus, researchers have found.

BOSTON (MedPage Today) -- Additional analysis has confirmed that a polymorphism in an interferon-related gene is strongly associated with responses to standard treatments for hepatitis C virus (HCV) infection, a researcher said here.

A small genetic change near the gene for interferon-lambda-3 doubles the chance of successful hepatitis C treatment, researchers said.

Genes for mental illness are hard to pinpoint, and a new study suggests one gene variant that was thought to be associated with depression may not predict risk after all

PARIS (MedPage Today) -- For the small percentage of MI patients younger than 45 who are homozygous for a certain gene variant, clopidogrel (Plavix) may be significantly less effective in secondary prevention, researchers reported here.
