Happy Pi Day everyone!
Big, bigger, biggest
It’s here, UK biobank first batch. 49,960 exomes, 4 million coding variants of which ~98.4% have frequency < 1%. The study should offer new perspectives on loss of function and actionable variants on a population scale.
We also have early insights from 53,831 diverse genomes from the NHLBI TOPMed Program, which aims to elucidate the genetic architecture and disease biology of heart, lung, blood, and sleep disorders.
Do we need a more diverse reference genome? Researchers compared the reference genome vs genomes from 154 individuals of 26 different ethnic populations.
We also had researchers assessing whether genetic variants associated with blood lipids, a major risk factor for CVD, are shared across different populations. They looked at African, Asian and European cohorts.
More Parkinson and Alzheimer GWASes
With interesting findings.
Five new genome-wide loci identified and pathway analysis shows that genetic variants affecting APP and Aβ processing are also associated with late-onset Alzheimer Diseases in a large 95k GWAS.
Variants identified with GWAS, specifically, PARK16 may predict disease progression in Parkinson’s patients.

Now we have TWAS: Transcriptome Wide Association Study
Study of the human transcriptome reveals tissue-dependent associations between genes and complex traits.
Moratorium on heritable genome editing
A practical and concrete initiative to stop gene editing until a robust international framework is in place, by some of the leading scientists in the field.
What do intronic and synonymous variants contribute?
Close to 5% of CACNA1F‐mediated inherited retinal disorders are explained by intronic and synonymous variants.
Clinical utility pre/post conception
Preconception screening of consanguineous couples for recessive and X-linked disorders using genomic sequencing is practicable, and is likely to detect many more at-risk couples than any targeted panel could achieve.

Genetics and drug development
Genetics can shed a light on adverse effects that are target-mediated vs off-target.
