New publication from the Wall Lab in PLoS Medicine
November 27, 2018. Felicitations to the Wall Lab for yesterday's publication of a super exciting paper (IMHO) in PLoS Medicine on mobile, machine-learning based detection of autism, which received top spot/front page billing!
New primer on deep learning in Nature Genetics and paper from the Zou Group in npg Digital Medicine
November 26, 2018. Congratulations to James Zou, et al, for today's publication of a primer on deep learning in genomics in Nature Genetics, with an accompanying interactive online tutorial. We hope this will be a useful resource for the community.
Also, felicitations on the feature story released last week by Stanford Medicine's New Center about a recent DeepTag paper (published in late October in npg Digital Medicine) Study authors included BDS members, Allen Nie, Ashley Zehnder, Arturo Lopez Pineda, Manuel Rivas, Carlos D. Bustamante, and James Zou, among others.
New publication in PLOS Genetics from the Rivas Lab
May 28, 2018. BDS faculty member Dr. Manuel Rivas's work, entitled "Insights into the genetic epidemiology of Crohn's and rare diseases in the Ashkenazi Jewish population," has been published today in PLOS Genetics.
UK Biobank data opens up window into genetics of disease
April 25, 2018. "A trove of genetic records from the UK Biobank was unleashed last July, and after mining the immense data set, scientists at Stanford have found strong evidence for 27 direct links between specific genetic mutations and a variety of human diseases.
Some of these mutations have never been associated with disease before, and some even seem to confer protection against disease, making them prime drug candidates.
The team's work, published in Nature Communications, focused in on a particular type of genetic oddity that halts proper protein formation before it's complete. It's called a protein-truncating variant, or a PTV. Manuel Rivas, PhD, a biomedical data scientist at Stanford, is the corresponding author."- Hanae Armitage, SCOPE Blog (Stanford School of Medicine)
AI can be sexist and racist — it’s time to make it fair
July 18, 2018. Computer scientists must identify sources of bias, de-bias training data and develop artificial-intelligence algorithms that are robust to skews in the data, argue James Zou (Stanford BDS) and Londa Schiebinger.
BMIR and DBDS Faculty Featured in New PanCan Papers
April 12, 2018. The Cancer Genome Atlas (TCGA) PanCan effort recently released a series of 27 papers. Published in various Cell journals, these papers mark the culmination and completion of the PanCancer Atlas Initiative (PanCan) and The Cancer Genome Atlas (TCGA) consortium. Faculty from Stanford’s Center for Biomedical Informatics Research (BMIR) and the Department of Biomedical Data Science (DBDS) contributed greatly to the completion of this large-scale PanCan initiative, which spanned a decade and analyzed over 11,000 tumors from 33 of the world’s most prevalent cancers.
Germline determinants of the somatic mutation landscape in 2,642 cancer genomes
November 16, 2017- Francisco de la Vega (Adjunct Professor in DBDS) and (DBDS Chair) Carlos D. Bustamante have, for the past few years, been working on a project with the International Cancer Genome Consortium - the Pan-Cancer Analysis of Whole-Genomes (PCAWG) group. The project involves the analysis of whole-genome sequencing data from cancer tumor specimens from over 2,600 cancer patients and matched normal tissue, and hundreds of researchers around the world organized in subgroups over 14 research themes. Drs De La Vega and Bustamante have, more specifically, been participating in the analysis of germline genomes to understand how the germline variants affect, among other things, the cancer somatic mutational process.
A milestone has recently been reached in the project, with the release of the germline team's manuscript at BioRxiv. This manuscript will be submitted soon for review, and will be published in a special issue in 3-4 months, with other consortium papers.
Interpretation of Neural Networks is Fragile
Fake news for AI by AI, in other words.
November 8, 2017- DBDS's Zou group just released a paper which, for the first time, demonstrates that interpretation of machine learning predictions are extremely fragile. The team, led by Ph.D. students Amirata Ghorbani and Abubakar Abid, showed that for two images that are visually identical and that are both predicted to be, for example, malignant, the machine learning algorithm can give two completely different explanations.
This is very disconcerting in practice because in order to trust machine learning predictions, researchers typically rely on its explanation for why certain predictions are made. This work shows that the explanation itself is highly unreliable.
Mosaic Mutations in Blood DNA Sequence Are Associated with Solid Tumor Cancers
July 6, 2017- This is the first of a couple of articles that will be coming out of the Rivas Lab and appearing in npj Genomic Medicine this summer 2017.
The editors of Genomic Medicine summarize the article as follows: "Having some abnormal blood cells with mutations that shorten the coding sequence of their genes increases one’s risk for solid tumors. Mark Daly and colleagues from the Broad Institute in Cambridge, Massachusetts, USA, used large genomic databases to test whether having blood cells both with and without genetic variants predicted to shorten the encoded protein — a phenomenon known as mosaic protein-truncating variants (PTVs) — was associated with developing a range of solid-tumor cancers. They studied DNA from around 8,000 people with cancer and 6,000 healthy controls. They confirmed previous reports linking these variants to breast and ovarian cancer, and extended the association to include tumors of the brain, skin and lungs. (Other studies have also shown that mosaic PTVs precede and predict the development of leukemia.) These results broadly connect cancer to blood DNA changes."
Stanford Daily Interview with DBDS Faculty James Zou
February 3, 2017- "In this series, The Stanford Daily sits down to talk with new faculty members on campus.
Assistant professor James Zou joined Stanford’s newly created biomedical data science department in the fall, teaching CS 273B: “Deep Learning in Genomics and Biomedicine” with Anshul Kundaje, assistant professor of genetics and computer science. The Daily sat down with Zou to discuss joining the Stanford community and his interests beyond his academic discipline."
