A review of some recently published scientific studies, including researchers at the University of Maryland Baltimore County identifying a single nucleotide that controls two forms of the HIV virus’ RNA.

The best-known genetic marker for Alzheimer’s disease is ApoE4 – a form of apolipoprotein E – which is a protein involved in repairing neurons injured by aging, stroke or other reasons.

Investigators at the Case Western Reserve University School of Medicine identified a previously unknown gene and the resultant protein that may potentially slow the progress of Alzheimer’s disease.

Many people worry about inheriting health problems from their parents, but a new approach to analyzing genetic contributions to disease risk suggests that for most diseases, commercial DNA tests are not the best way to assess the odds.
