TL;DR: In a genome-wide search for CNVs associating with schizophrenia, a population-based sample was used to identify de novo CNVs by analysing 9,878 transmissions from parents to offspring and three deletions significantly associate with schizophrenia and related psychoses in the combined sample.

TL;DR: A study of genome-wide mutation rates by sequencing the entire genomes of 78 Icelandic parent–offspring trios at high coverage shows that the diversity in mutation rate of single nucleotide polymorphisms is dominated by the age of the father at conception of the child.

TL;DR: An association between myocardial infarction and a common sequence variant on chromosome 9p21 was associated with the disease with high significance and approximately 21% of individuals in the population are homozygous for this variant, and their estimated risk of suffering myocardious disease is 1.64 times as great as that of noncarriers.

TL;DR: In a population-based study in Iceland, children under 10 years of age and females had a lower incidence of SARS-CoV-2 infection than adolescents or adults and males and the proportion of infected participants identified through population screening remained stable for the 20-day duration of screening.

TL;DR: A second genetic variant in the 8q24 region that, in conjunction with another variant recently discovered, accounts for about 11%–13% of prostate cancer cases in individuals of European descent and 31% of cases in African Americans is reported.
