New hereditary breast cancer gene discovered

26.04.2007
A new hereditary breast cancer gene has been discovered by scientists at the Lundberg Laboratory for Cancer Research and the Plastic Surgery Clinic at the Sahlgrenska Academy in Sweden.

The researchers found that women with a certain hereditary deformity syndrome run a nearly twenty times higher risk of contracting breast cancer than expected.

Several research teams around the world have long been searching for new hereditary breast cancer genes, but thus far few have been found.

"Our findings are extremely important, providing new knowledge of hereditary cancer genes and how they can cause breast cancer. The discovery also makes it possible to uncover breast cancer in women who have a predisposition for Saethre-Chotzen malformation syndrome," says Göran Stenman.

By detailed mapping of families with Saethre-Chotzen syndrome, the Göteborg scientists have now found that women with this syndrome have an elevated risk of contracting breast cancer. Saethre-Chotzen is a syndrome that primarily involves malformations of the skull, face, hands, and feet. The syndrome is caused by mutations in a gene called TWIST1.

"Our findings show that women with this syndrome run a nearly twenty times greater risk of contracting breast cancer than expected. Moreover, many of the women were young when they were affected by breast cancer," says Göran Stenman.

The findings of the study show that women with this syndrome should be receive early mammograms in order to discover breast cancer at an early stage.

"We have already started to use this new knowledge in our work with patients and now recommend regular mammograms for young women with this syndrome. Several early cases of breast cancer have already been uncovered with mammography," says Pelle Sahlin, chief physician at the Plastic Surgery Clinic.

The scientists are now going to perform various experiments to chart the mechanism of how TWIST1 increases the risk of breast cancer. Studies are also under way to find out what proportion of cases of hereditary breast cancer are caused by mutations in the TWIST1 gene.

The study was carried out with funding from the Swedish Cancer Society.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
