A general patent policy concern is that if exclusive rights are too strong, then there will be a chilling effect on scientific research and instead of promoting the advancement of arts and science, patents would act to deter advance. AMP asserts that scientific research has been chilled because Myriad holds patents to the BRCA1/2 genes. In fact, AMP notes that 46% of geneticists felt that their work was delayed or limited by gene patents. The Academics also assert gene patents prevent the development of a comprehensive genetic test, forcing patients and providers to use multiple tests, decreasing the efficiency, effectiveness, and timeliness.
Many health care providers do not have either the knowledge or the tools they need in order to apply genetic information in their day-to-day practices. This lack of support is contributing to a substantial delay in the translation of genetic research findings, when appropriate, into improvement in patient outcomes within the health care system. Although the need to improve genetics knowledge among health care providers is clear, the best approaches to educating health care providers in a way that produces meaningful changes in clinical practice are not, especially given the competing coursework and training needs that exist in today's increasingly complex health care settings.
To examine the potential and the challenges of providing genetics education, the Roundtable on Translating Genomic-Based Research for Health of the Institute of Medicine hosted a workshop on August 18, 2014. The workshop examined a variety of approaches that could improve the teaching of genetics in the graduate and continuing education of health professionals; these approaches included online and interactive instruction, just-in-time approaches, the development of clinical decision-support tools, and the incorporation of genetics requirements into licensing and accreditation. This report summarizes the presentations and discussion of the event.
Your genes play an important role in your health, but so do your behaviors and environment, such as what you eat and how physically active you are. Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence.
Cancer patients face a mountain of stress. As they are hearing unwelcome, life-changing news, they must also understand detailed medical information to make time-sensitive decisions about surgery and/or chemotherapy with their healthcare providers. Genetic counselors (GCs) are medical professionals trained in both genetics and counseling who are often part of the cancer care team, providing education and support for patients through their journey. Myriad partners with GCs to provide vital information to help guide medical decisions.
The field of neurogenetics can be challenging to navigate because of the rapid pace of genetic discovery and growing selection of available tests. Genetic testing can be complex and collaboration with a genetic counselor can both help to delineate the appropriate testing and provide support to patients and providers. If a genetic counselor is not available, referral to a specialized neuromuscular disease center may be appropriate.
This up-to-date and comprehensive textbook is essential reading material for advanced undergraduate and graduate students with a course module in genetics and developmental biology. The book provides clear, concise, and rigorous foundational concepts of genetics. It opens with an introductory chapter that provides an overview of genetics. The book includes separate and detailed sections on classical genetics, molecular genetics, and population genetics. It covers basic and foundational principles such as Mendelian genetics, chromosomal theory, transcription, translation, mutation, and gene regulation. It further includes chapters on advanced topics such as molecular genetic techniques, genomics, and applied molecular genetics. The concluding section includes chapters on population genetics, developmental genetics, and evolutionary genetics. The chapters are written by authors with in-depth knowledge of the field.
The book is replete with interesting examples, case studies, questions and suggested reading. It is useful to students and course instructors in the field of human genetics, developmental biology, life sciences, and biotechnology. It is also meant for researchers who wish to further their understanding about the fundamental concepts of genetics.
In conclusion, we demonstrated a framework to generate RWE using RWD from different clinical sources. Rule-based NLP system achieved the best performance for resolving contextual variability when extracting RWD from unstructured clinical notes. Data quality issues such as incompleteness and discrepancies exist thus manual data cleaning is needed before further analysis can be performed. Finally, we were able to use cleaned RWD to evaluate the real-world utility of genetic information to initiate a prescription of targeted therapy.
Our cohort included 196 women cancer (breast, ovary, cervix, and uterus) patients that have conducted Foundation Medicine genetic tests with reports returned back to Mayo Clinic. Foundation Medicine, Inc. offered somatic genetic tests to qualifying patients across all solid tumors. With research authorization, we collected their genetic reports from Foundation Medicine, Inc. as well as unstructured clinical notes until March 31, 2020 from Mayo Clinic clinical data warehouse. The data warehouse integrated clinical notes from Mayo Clinic historical notes (Minnesota, Arizona, Florida, Mayo Clinic Health System notes), and Mayo Clinic Epic notes (Minnesota from May 2018, Arizona, Florida from Oct 2018, Mayo Clinic Health System from 2017). This research project was reviewed by the Mayo Clinic Institutional Review Board.
Figure 4 displayed a timeline view of a single patient (Patient 3). In this view, we could see that this patient had a discussion with the physician about the risk of having BRCA1/2 and the benefits of having the genetic test on 08/30/2017. After the discussion, the patient took the test, and the results returned positive. But there was a discrepancy in clinical notes documentation where it first documents the results as a positive mutation in BRCA2 but later revised it to BRCA1 (rectangled). This example demonstrated the benefit of using a timeline view to perform data quality checks in the future.
Our genetic information extraction system revealed discrepancies and missingness of genetic data in EHRs: (1) BRCA1/2 mutation information was captured 75% and VUS only 20.8% (2) certain data fields (e.g. variant type or source) within clinical notes have a low rate of capture. Although we considered some of these fields to be important, such as VUS as well as detailed variant information, the low rate of documentation indicates that such data are not essential in the routine management of patients. Indeed, oncology providers only need to know whether a specific gene has a pathogenic mutation to determine eligibility for FDA-approved targeted agents; the specific variant details do not contribute to clinical decision making.
In our work, we demonstrated a framework to generate RWE using RWD from different clinical sources: (1) Applying the NLP system that can resolve contextual variability to extract RWD from unstructured clinical notes. (2) Examination of data quality issues such as incompleteness and discrepancies in retrieved data. (3) Due to limited data quality, manual data cleaning is needed before further analysis can be performed. (4) Using cleaned RWD to generate RWE. From our use case, we found that currently, the rule-based NLP system achieved the best performance. Data quality issues such as incompleteness and discrepancies exist and vary by data type. Finally, we were able to use cleaned RWD to show that the real-world association of BRCA1/2 and discussion/prescription of PARP inhibitor is significant.
Lecture notes from my graduate course in population genetics. Topics covered include basic principles of Hardy-Weinberg, population structure, drift, mutation, selection, quantitatitve genetics, molecular evolution, and phylogeography.
The first link below will take you to the course website. The notes are from the Fall 2021 edition of the course. The second link is to the release page on Github. There you'll find links to the most recent version of the notes (v4.1) that will provide a ZIP file (or a gzipped tar ball) of the files used to produce this PDF.
Go to class, take notes by hand (in telegraphic style, abbreviating as needed), and copy your notes in complete sentences and legible handwriting as soon as possible thereafter. Words written by hand are retained in memory better than words typed on a keyboard.
