Deep sequencing captures genetic variants for vascular anomalies
Children’s Hospital of Philadelphia (CHOP) researchers found that deep sequencing of the genome in the tissue samples and cell-free DNA of patients with potentially life-threatening vascular anomalies revealed genetic variants previously not captured by conventional genetic sequencing methods. The research, published Thursday in the journal Nature Medicine, led to improvements in over 60% of the patients placed on targeted therapies related to these newly found genetic variants. Read More
Single-cell RNA sequencing data reveals T cells linked to cancer immunotherapy resistance
Single-cell RNA sequencing data has revealed an immune signature associated with non-responses to checkpoint inhibitors that may be a driver of resistance to immunotherapy. Read More
Gene editing tool may reduce antimicrobial resistance spread
A tool that could help reduce the spread of antimicrobial resistance shows early promise. In an article published Thursday in Microbiology, researchers describe the use of CRISPR technology to eliminate resistance in a wide range of bacteria. Read More

Strategic self-limiting production of infectious HIV particles by CRISPR
Temple University researchers found that genetic alterations that give rise to a rare congenital disorder known as MOGS-CDG paradoxically also prevent HIV infection from spreading in permissive cells -- i.e., cells that support viral replication. The new approach, described Friday in Molecular Therapy – Nucleic Acids, harnesses this unusual protective ability in a novel gene-editing strategy aimed at eliminating HIV-1 infection without adversely effecting cell mortality.

FDA approves first topical gene therapy for treatment of wounds in patients with dystrophic epidermolysis bullosa
The U.S. Food and Drug Administration (FDA) said on Friday it has approved Vyjuvek, a herpes-simplex virus type 1 (HSV-1) vector-based gene therapy, for the treatment of wounds in patients six months of age and older with dystrophic epidermolysis bullosa (DEB) and with mutations in the collagen type VII alpha 1 chain (COL7A1) gene.

Alzheimer’s disease and modifiable risk factors: Genetic associations revealed
A genetic association study comparing participants with Alzheimer’s disease and control participants without Alzheimer’s disease found novel genetic associations between high high-density lipoprotein (HDL) cholesterol concentrations and high systolic blood pressure and a higher risk of Alzheimer’s disease.
