The Tiresias complex: Huntington's disease as a paradigm of testing for late-onset disorders. (17/105)

Huntington's disease represents the first disorder for which positional cloning techniques successfully localized an autosomal gene--in 1983. Events since that time have proved the gene recalcitrant to identification and characterization. Since 1986, presymptomatic and prenatal testing for Huntington's disease has been available internationally, although on a limited basis. Testing for Huntington's disease provides an excellent model for designing service programs for genetic testing for late-onset, fatal disorders, particularly when the gene is not yet in hand and no therapeutic intervention is possible. Special training and precautions must be in place before presymptomatic genetic testing should be offered.  (+info)

State legislative efforts to regulate use and potential misuse of genetic information. (18/105)

The purpose of this study was to review existing and proposed legislation specifically intended to regulate the collection, use, and potential misuse of genetic data. The study encompasses laws relating to confidentiality, informed consent, discrimination, and related issues. It excludes from consideration legislation relating to medical records generally that may bear indirectly on genetic information. It also excludes both legislation relating to the regulation of DNA data collection for law enforcement purposes and state laws relating to the confidentiality of data collected by newborn-screening programs. While relatively few laws that explicitly regulate the treatment of genetic information have been enacted to date, a considerable amount of activity is currently underway in the nation's legislatures. Although most of the bills under consideration are not comprehensive in scope, they reflect a growing societal awareness that the uncontrolled dissemination and use of genetic data entails significant risks.  (+info)

How (not) to protect genomic data privacy in a distributed network: using trail re-identification to evaluate and design anonymity protection systems. (20/105)

The increasing integration of patient-specific genomic data into clinical practice and research raises serious privacy concerns. Various systems have been proposed that protect privacy by removing or encrypting explicitly identifying information, such as name or social security number, into pseudonyms. Though these systems claim to protect identity from being disclosed, they lack formal proofs. In this paper, we study the erosion of privacy when genomic data, either pseudonymous or data believed to be anonymous, are released into a distributed healthcare environment. Several algorithms are introduced, collectively called RE-Identification of Data In Trails (REIDIT), which link genomic data to named individuals in publicly available records by leveraging unique features in patient-location visit patterns. Algorithmic proofs of re-identification are developed and we demonstrate, with experiments on real-world data, that susceptibility to re-identification is neither trivial nor the result of bizarre isolated occurrences. We propose that such techniques can be applied as system tests of privacy protection capabilities.  (+info)

The right not to know: an autonomy based approach. (21/105)

The emerging international biomedical law tends to recognise the right not to know one's genetic status. However, the basis and conditions for the exercise of this right remain unclear in domestic laws. In addition to this, such a right has been criticised at the theoretical level as being in contradiction with patient's autonomy, with doctors' duty to inform patients, and with solidarity with family members. This happens especially when non-disclosure poses a risk of serious harm to the patient's relatives who, without that vital information, could be deprived of preventive or therapeutic measures. This paper argues, firstly, that individuals may have a legitimate interest in not knowing their genetic make up to avoid serious psychological consequences; secondly, that this interest, far from being contrary to autonomy, may constitute an enhancement of autonomy; thirdly, that the right not to know cannot be presumed, but must be "activated" by the individual's explicit choice, and fourthly, that this is not an absolute right, in the sense that it may be restricted when disclosure to the patient is necessary in order to avoid a risk of serious harm to third persons.  (+info)

An evaluation of the current state of genomic data privacy protection technology and a roadmap for the future. (22/105)

The incorporation of genomic data into personal medical records poses many challenges to patient privacy. In response, various systems for preserving patient privacy in shared genomic data have been developed and deployed. Although these systems de-identify the data by removing explicit identifiers (e.g., name, address, or Social Security number) and incorporate sound security design principles, they suffer from a lack of formal modeling of inferences learnable from shared data. This report evaluates the extent to which current protection systems are capable of withstanding a range of re-identification methods, including genotype-phenotype inferences, location-visit patterns, family structures, and dictionary attacks. For a comparative re-identification analysis, the systems are mapped to a common formalism. Although there is variation in susceptibility, each system is deficient in its protection capacity. The author discovers patterns of protection failure and discusses several of the reasons why these systems are susceptible. The analyses and discussion within provide guideposts for the development of next-generation protection methods amenable to formal proofs.  (+info)

Health care policy issues as a result of the genetic revolution: implications for public health. (23/105)

The genetic revolution has spawned 4 distinct issues of universal importance to health care policy and society: genetic privacy, regulation and standardization of genetic tests, gene patenting, and education. Adequate policy advancements for these 4 areas are lacking. Stringent controls must be placed on individual health records to prevent their misuse. Genetic testing within the clinical setting should undergo thorough evaluation before it is implemented. Regulations are needed to prevent the monopolization of DNA sequences. Society and health care professionals must be educated about the scope of genetic testing because current trends indicate that genetic and molecular assessments are destined to become a routine component of health care.  (+info)

A survey of the SWISS researchers on the impact of sibling privacy protections on pedigree recruitment. (24/105)

To understand the perceptions and attitudes about privacy safeguards in research and investigate the impact of letter-based proband-initiated contact on recruitment, we surveyed researchers in the Siblings With Ischemic Stroke Study (SWISS). All 49 actively recruiting sites provided at least 1 response, and 61% reported that potential probands were enthusiastic. Although 66% of researchers valued proband-initiated contact, only 23% said that probands viewed this strategy as important to protecting the privacy of siblings. A substantial minority of researchers (37%) said the strategy impeded enrollment, and 44% said it was overly burdensome to probands.  (+info)
