The Genomewide Association Study The genomewide association study is typically based on a case–control design in which single-nucleotide polymorphisms
(SNPs) across the human genome are genotyped.
Panel A depicts a small locus on chromosome 9, and thus a very small fragment of the genome.
In Panel B, the strength of association between each SNP and disease is calculated on the basis of the prevalence of each SNP in
cases and controls. In this example, SNPs 1 and 2 on chromosome 9 are associated with disease, with P values of 10−12 and
10−8, respectively.
The plot in Panel C shows the P values for all genotyped SNPs that have survived a quality-control screen, with each
chromosome shown in a different color. The results implicate a locus on chromosome 9, marked by SNPs 1 and 2, which are
adjacent to each other (graph at right), and other neighboring SNPs

Subclinical (cryptic) latency
(1) to predict the likelihood of developing disease;
(2) to estimate the length of the asymptomatic
period;
(3) to provide predictive information about disease
course, severity, and complications;
(4) to serve as a warning to avoid potential disease-
triggering factors;
(5) to identify high-risk individuals who might be
suitable candidates for preventive intervention
trials
Impacts to be assumed for
the practical implementation of
predictive biomarkers and biopredictors
into PPPM
This illustrates a functional state of a cell
at the level of metabolism illustrating all
metabolic pathways in the cell at a given
time span
• How the human genome has opened up a broad
spectrum of predictive approaches for genetic
diseases by screening individual genes, SNPs,
and haplotypes
• How protein and RNA microarrays are
providing new insight into the nature, subclinical
and clinical courses, and prognosis of certain
ongoing diseases
• How autoantibodies (autoAbs) which now are
known to be present years before the clinical
onset of a number of autoimmune diseases are
being used as predictive biomarkers to enter
high-risk subjects into therapeutic intervention
trials
Two key objectives of PPPM are:
(i) detection of subclinical
abnormalities with a selection of
suitable pharmacotherapeutic
targets for the next step of PPPM
protocol, i.e., drug-based
prevention
(ii) drug-based correction of the
abnormalities detected under
preventive measures.
PPPM thus uses diagnostic tests of newer
generations, particularly genomic, proteomic, and
metabolomic biomarkers, to individually determine
the health conditions a person is predisposed to and
to reveal the agents of the probable or the already
existing pathological processes.
The predictive branch is mainly designed
to meet the interests of healthy individuals, its
purpose being to determine whether susceptibility to
a particular disease is increased or not.
Preventive medicine is aimed at taking
measures to avoid disease development rather than
cure or treat it on manifestation
Personalized medicine proposes the
customization of healthcare, with all decisions and
practices being tailored to the individual patient by the
mutual integration of clinical information, stable and
dynamic genomics, and molecular phenotyping through
bioinformatics.
Personalized medicine generally
promises to result in both higher quality in treatment for
individual patients and in lower costs in healthcare since
patients will be offered only such therapies that are more
effective for them and treatments that will not be safe or
effective will be avoided. Recent advancements in
biomedical and genomic sciences have paved the way to
translate such research into clinical practice and health
policies.

Differential Roles of Risk Loci in the Pathogenesis of T1D
Many risk loci for
IDDM1 may exert
their effects through
the immune system
(HLA, presumably).
Within the immune
response, these
genes can act at
multiple levels,
affecting the
establishment of the
immune repertoire,
the function of cell
types in the immune
system, or the
regulation of
cellular responses
that can lead to
autoimmunity.

Three different steps are described during cancerogenesi:
initiation is a rapid and irreversible DNA lesion which
occurs after exposure to a carcinogen (physical
carcinogen, chemical carcinogen, viral carcinogen)
promotion is due to prolonged, repetitive or continuous
exposure to substances which maintain and stabilise the
initiated lesion,
progression is the acquisition of non controlled
multiplication properties, independence acquisition, loss of
differentiation, local invasion and metastasis.
• The strategy of preventive therapy should contain, at least, two critical steps.
For chronic autoimmune diseases:
(i) arrest of autoagression; and,
(ii) restoration of structure and functions of the
tissue affected.
For cancerogenesis:
(i) prevention of the initiation and metastatic
activity; and,
(ii) restoration of structure and functions of the
tissue affected.
• Prevention of the initiation of the cancer process involves the
protection of cells from carcinogenic agents like tobacco, benzol,
various chemical products, radiation, and so on). Prevention is
dictated by knowledge acquired through human epidemiological
studies as well as experimental cancers in animals.
• Preventing the promotion of the cancer process also involves
protecting the organism from various products and situations, like
alcohol, tobacco, viruses, local irritation processes, and so on).
Prevention results from the same type of epidemiological and
experimental studies. Knowledge of other diseases linked to
developing cancers (such as genital infections or hereditary
syndromes) also facilitates cancer prevention.
• Preventing the progression of cancer is possible through the
same studies but also by active, well designed policies for the
screening of pre-cancerous lesions and small cancers, when policies
are applicable.
• The strategy mentioned can be
accomplished by:
•gene therapy, or
•stem cells technologies.
• System approach to the formation of an innovative
infrastructure regarding predictive and preventive
algorithms is an ultimate approach that will contribute
to the modernization of the world healthcare services
drastically. Our challenge is that the new guidelines
should create the robust juristic and economic
platforms for advanced medical services utilizing the
cost-effective models of risk assessments followed
by tailored preventive treatments focused on the
precursor stages of chronic diseases. Recently
developed economical models clearly demonstrate
the efficacy of PPPM, if introduced as the integrative
medical approach into the healthcare services.
• Individuals to be under regular
monitoring that helps to detect
pathological shifts at subclinical
stages of a disease have a higher life
expectancy and are able-bodied up
to 8–15 years more than those under
traditional treatment. This means that
the society saves more than
US$20,000–40,000 per person
annually.
• In general, we see the following main obstacles to
the advancement of PPPM:
• the scientific challenges (a poor
understanding of molecular mechanisms or a lack of
molecular biomarkers, for example);
• the economic challenges (poorly
aligned incentives), and
• operational issues in public healthcare
systems.
The operational issues can often be largely resolved
within a particular stakeholder group, but correcting the incentive
structure and modifying the relationships between stakeholders
is more complex
The true era of PPPM, while perhaps
decades away, is impacting the pharmaceutical
and healthcare industries today.
The Saint Trinity, in particular,
• translational research,
• biomarker-based studies and
• careful patient segmentation in
clinical trials,
have led to successes such as new biomarker-
based drugs; drugs with companion diagnostics
and highly targeted therapies.

Who should be screened ?
Should screening include the general population, or rather first-degree relatives of patients, genetically prone HLA groups? Those special groups may benefit more from the screening compared to the general population. Accordingly, testing high-risk groups may change the positive diagnostic or predictive value of the panel tests used.
When should individuals
be screened?
The best age for screening varies in different diseases. For example, while cancer-associated biomarkers or diabetes-associated antibodies appear by 3-5 years of age, thyroid antibodies uncommonly appear before 20 years of age.
Which biomarkers
should be screened for?
Different biomarkers appearing in the same diseases have different diagnostic and predictive values as individual screening test, as well as in combination.
How should the screening
be performed?
Specificity and sensitivity of different laboratory assays must be considered.
How should we interpret
changes found outside of genes?
No answer yet…
Core question:
Who should be informed?
Once biomarkers have been found, a risk of future disease is established. This information may have great implication regarding one’s future, and thus its distribution should be handled with great care. Should family members be informed, especially taking into account their associated risk?
How should we effectively communicate
the results to patients in ways that will
improve health without inducing neurosis?
No comments.
Should one be informed to expect a disease for
which, at least currently, there is no cure ?
No answer yet.
Should employment authorities be notified?
Should such information be available to all
caring physicians?
Should military authorities be informed? Or
should one be obligated to inform
insurance companies?

PPPM is driving key changes in the biopharmindustry The true era of personalized medicine, while perhaps decades away, is impacting the pharmaceutical and
healthcare industries today. Most notably, this vision is impacting the landscape of how clinical research and
trials are conducted. Translational research, biomarker-based studies and careful patient segmentation in clinical
trials, have led to successes such as new biomarker based drugs; drugs with companion diagnostics and highly
targeted therapies. Fundamental to biomarker research is access to quality biospecimens that have been
extensively annotated with clinical, molecular and patient data. While many organizations have invested heavily
in the IT infrastructure of biospecimen management, or biobanking, such systems are facing challenges to
effectively drive investigative biomarker-based research
