What Does It Mean When Everyone Can Get Their DNA Sequenced?
K Miller, Discover, December 22, 2019

DTC companies don’t conduct clinical testing, so their labs don’t have to meet the same strict federal standards as medical facilities. The companies typically post disclaimers stating that their products are not for medical use. Yet more and more patients are asking physicians for advice based on DTC test results, leading doctors into largely uncharted territory.

Autism risk in offspring can be assessed through quantification of male sperm mosaicism
MW Breus et al, Nature Medicine, December 23, 2019

We measured sperm mosaicism using deep-whole-genome sequencing, for variants both present in an offspring and evident only in father’s sperm, and identified single-nucleotide, structural and short tandem-repeat variants. We found that mosaicism quantification can stratify autism spectrum disorders recurrence risk due to de novo mutations.

Paternal sperm DNA mosaicism and recurrence risk of autism in families

Genomic risk score offers predictive performance comparable to clinical risk factors for ischaemic stroke.
Abraham Gad et al. Nature communications 2019 Dec (1) 5819

Using a meta-scoring approach, we develop a metaGRS for ischaemic stroke (IS). The metaGRS hazard ratio for IS (1.26, 95% CI 1.22–1.31 per metaGRS standard deviation) doubles that of a previous GRS, identifying a subset of individuals at monogenic levels of risk: the top 0.25% of metaGRS have three-fold risk of IS.
