| Open AccessPolygenic background modifies penetrance of monogenic variants for tier 1 genomic conditions
Genetic variation predisposes to disease via monogenic and polygenic risk variants. Here, the authors assess the interplay between these types of variation on disease penetrance in 80,928 individuals. In carriers of monogenic variants, they show that disease risk is a gradient influenced by polygenic background.

| Open AccessEuropean polygenic risk score for prediction of breast cancer shows similar performance in Asian women
Polygenic risk scores predict the likelihood that an individual will develop a certain cancer, however these are often specific for a given population. Here, the authors show that a risk score developed to assess the risk of breast cancer in European women can also predict risk in Asian populations.

| Open AccessA rare variant of African ancestry activates 8q24 lncRNA hub by modulating cancer associated enhancer
Genetic variants on chromosome 8q24 are associated with prostate cancer risk in men of African ancestry. Here the authors show that one of these variants, rs72725854 alters the enhancer activity in its region, which upon androgen stimulation, activates multiple oncogenic lncRNAs and c-myc.

Genes that modulate the cytoskeleton have been associated with increased cell proliferation and migration. Here, the authors show that AVIL, an actin regulatory protein, is overexpressed in glioblastomas and mediates oncogenic effects through regulation of FOXM1 stability and LIN28B expression.

| Open AccessLooking backward in time to define the chronology of metastasis
The timing of cancer metastasis has implications for treatment and prevention. Traditional forward-time views of metastasis assume it occurs late during evolution. However, looking backward in time reveals metastasis often occurs prior to clinical detection of primary tumors.

| Open AccessIdentification of cancer sex-disparity in the functional integrity of p53 and its X chromosome network
There is disproportionally high cancer prevalence in males. Here, the authors analyse the tumour suppressor p53 in sporadic cancers, highlighting a higher incidence of its mutation in males. Males are further disadvantaged by a failure to shield against the expression of damaged X-linked genes in p53-networks. These factors likely contribute to sex-disparity.
