Buyer Beware

In her personal health column in the New York Times, Jane Brody writes that for consumers who are using direct-to-consumer genetic tests to discover their medical risks, testing is "fraught with potential dangers." Those dangers range from receiving false reassurance to a lack of federal oversight to uncertainty about clinical validity. " For the moment, regardless of what a genetic test might show, the best course is to follow the usual recommendations about adopting healthful living habits and avoiding exposure to noxious substances," Brody writes.

The direct-to-consumer field continues to grow. Illumina announced yesterday that they delivered their first personal genome sequencing to Hermann Hauser, as our sister publication In Sequence reports. At Genetic Future, Daniel MacArthur says this is "a shot across the bow for Complete Genomics" which just raised $45 million to build a personal genome sequencing center.

Genetic Tests Lead to Potential Prognostic Variants in Dutch Children With Dilated Cardiomyopathy

Researchers in Circulation: Genomic and Precision Medicine found that the presence of pathogenic or likely pathogenic variants was linked to increased risk of death and poorer outcomes in children with pediatric dilated cardiomyopathy.

Fragile X Syndrome Mutations Found With Comprehensive Testing Method

Researchers in Clinical Chemistry found fragile X syndrome expansions and other FMR1 mutations with ties to the intellectual disability condition using a long-range PCR and long-read sequencing approach.

Team Presents Strategy for Speedy Species Detection in Metagenomic Sequence Data

A computational approach presented in PLOS Computational Biology produced fewer false-positive species identifications in simulated and authentic metagenomic sequences.
