Finding causal genes underlying risk for coronary artery disease
PL Auer, Nature Genetics, December 6, 2022

Previous genome-wide association studies of coronary artery disease (CAD) have discovered multiple susceptibility loci but have largely failed to uncover causal genes. A new study identifies hundreds of likely causal genes underlying the genetic risk for CAD.

Discovery and systematic characterization of risk variants and genes for coronary artery disease in over a million participants
KG Aragam et al, Nature Genetics, December 6, 2022

The discovery of genetic loci associated with complex diseases has outpaced the elucidation of mechanisms of disease pathogenesis. Here we conducted a genome-wide association study (GWAS) for coronary artery disease (CAD) comprising 181,522 cases among 1,165,690 participants of predominantly European ancestry. We detected 241 associations, including 30 new loci. Cross-ancestry meta-analysis with a Japanese GWAS yielded 38 additional new loci.

High molecular diagnostic yields and novel phenotypic expansions involving syndromic anorectal malformations
RB Deloge et al, EJHG, December 6, 2022

Evidence suggests that genetic factors contribute to the development of anorectal malformations (ARMs). However, the etiology of the majority of ARMs cases remains unclear. Exome sequencing (ES) may be underutilized in the diagnostic workup of ARMs due to uncertainty regarding its diagnostic yield. In a clinical database of ~17,000 individuals referred for ES, we identified 130 individuals with syndromic ARMs. A definitive or probable diagnosis was made in 45 of these individuals for a diagnostic yield of 34.6% (45/130).

Genome sequencing with gene panel-based analysis for rare inherited conditions in a publicly funded healthcare system: implications for future testing
LJ Hocking et al, EJHG, December 6, 2022

We sought to investigate the Genomics England 100,000 Genomes Project diagnostic utility to evaluate genome sequencing for in rare, inherited conditions. Four regional services recruited 999 individuals from 394 families in 200 rare phenotype categories, with negative historic genetic testing. New diagnoses were made in 23% cases – 19% in genes implicated in disease at the time of variant prioritisation, and 4% from later review of additional genes.
