TL;DR: A five base-pair deletion in exon 9 of BRCA2 in an affected male from the male breast cancer family2 is described, indicating a founder effect in this population of males.
Abstract: The BRCA2 gene on chromosome 13 has been shown to be associated with familial male and female breast cancer. Here we describe a study on BRCA2 in 21 Icelandic families, including 9 with male breast cancer. We have previously reported linkage to the BRCA2 region in an Icelandic male breast cancer family1 and subsequently found a strong indication of linkage to BRCA2 and the same BRCA2 haplotype in breast cancer cases from 15 additional families, indicating a common origin. We describe a five base-pair deletion in exon 9 of BRCA2 in an affected male from the male breast cancer family2. The same mutation occurs in all the families with the shared BRCA2 haplotype indicating a founder effect. Among mutation carriers there are 12 males with breast cancer, which accounts for 40% of all males diagnosed with breast cancer in Iceland over the past 40 years. Three of them have no family history of breast cancer indicating that this mutation may have variable penetrance. The same BRCA2 mutation appears to be associated with different cancer phenotypes in this population including male and female breast cancer, prostate cancer, pancreas cancer and ovarian cancer.

TL;DR: The authors found that official intervention in youth has a significant, positive effect on crime in early adulthood, and this effect is partly mediated by life chances such as educational achievement and employment, and found considerable support for this revised labeling approach.
Abstract: Scholars have recently revitalized labeling theory as a developmental theory of structural disadvantage. According to this approach, official intervention increases the probability of involvement in subsequent delinquency and deviance because intervention triggers exclusionary processes that have negative consequences for conventional opportunities. The theory predicts that official intervention in adolescence increases involvement in crime in early adulthood due to the negative effect of intervention on educational attainment and employment. Using panel data on urban males that span early adolescence through early adulthood, we find considerable support for this revised labeling approach. Official intervention in youth has a significant, positive effect on crime in early adulthood, and this effect is partly mediated by life chances such as educational achievement and employment.

TL;DR: This large, multi-ethnic genome-wide association study identifies 97 loci significantly associated with atrial fibrillation that are enriched for genes involved in cardiac development, electrophysiology, structure and contractile function.
Abstract: Atrial fibrillation (AF) affects more than 33 million individuals worldwide1 and has a complex heritability2. We conducted the largest meta-analysis of genome-wide association studies (GWAS) for AF to date, consisting of more than half a million individuals, including 65,446 with AF. In total, we identified 97 loci significantly associated with AF, including 67 that were novel in a combined-ancestry analysis, and 3 that were novel in a European-specific analysis. We sought to identify AF-associated genes at the GWAS loci by performing RNA-sequencing and expression quantitative trait locus analyses in 101 left atrial samples, the most relevant tissue for AF. We also performed transcriptome-wide analyses that identified 57 AF-associated genes, 42 of which overlap with GWAS loci. The identified loci implicate genes enriched within cardiac developmental, electrophysiological, contractile and structural pathways. These results extend our understanding of the biological pathways underlying AF and may facilitate the development of therapeutics for AF.
