Cell Theory
• All organisms are
composed of one or
more cells.
• Cells are the smallest
living units of all living
organisms.
• Cells arise only by
division of a previously
existing cell.

The human genome comprises the information contained in one
set of human chromosomes which themselves contain about 3
billion base pairs (bp) of DNA in 46 chromosomes (22
autosome pairs + 2 sex chromosomes). The total length of DNA
present in one adult human is calculated by the multiplication of
(length of 1 bp)(number of bp per cell)(number of cells in the body)

Defining Epigenetics
• Reversible changes in gene
expression/function
• Without changes in DNA
sequence
• Can be inherited from
precursor cells
• Epigenetic information is
included in the epigenome
• Allows to integrate intrinsic
with environmental signals
(including diet)

26. Lab for Bioinformatics and computational genomics
Epigenetics
• Epigenetics is essentially the
study of how our environment
impacts traits acquired within
our lifetimes, altering certain
gene expressions which may
then be passed on to future
generations
• That is, what we do to our own
bodies may affect our children
& grandchildren more than we
thought.

Everyone should have the power and legitimacy to
be able to discover, develop and find new things
about their own genome data.
Intelligent exploration, experimentation and trial to
push the boundaries of knowledge are a basic
human right.
PGMv2: Personal Genomics Manifesto
56. Lab for Bioinformatics and computational genomics
Personal genome data access should be
affordable to all irrespective of nationality, gender,
social background or any other circumstance.
Not having access to a personal genetic test is in
itself a new kind of discrimination.
PGMv2: Personal Genomics Manifesto
57. Lab for Bioinformatics and computational genomics
Whether one wants to share genome data or keep it
private should be a matter of personal choice.
Whatever attitude a person has towards personal
genome privacy, it should be utterly respected.
Corporate interest can never compromise any human
right. Laws must fully protect individual human rights of
equality for every person, irrespective of predicted risks
from genetic data.
PGMv2: Personal Genomics Manifesto
58. Lab for Bioinformatics and computational genomics
Stating that genetic tests merely provide non-
clinical information misses the point of what
personal genomics is all about.
Most genomic information is uninterpretable and
may well be meaningless. But those are not
reasons to deny it to people.
Genetic test results are not unrelated to
someone’s health, one’s ability to respond to
certain drugs and one’s ethnic ancestry.
PGMv2: Personal Genomics Manifesto
59. Lab for Bioinformatics and computational genomics
Education in risks and opportunities for personal
genetic testing should be the primary aim of
policy makers.
Restricting access to interested people makes
no sense and it is virtually impossible to ensure.
Access to personal genomics data and tools for
its interpretation should become accessible to
everyone.

Customization-Case Study
Here, we define epigenetics and depict the relationship between the genome and the epigenome
The genome is hereditary information encoded in the DNA and the epigenome is the way cells express the encoded information1
The epigenome is a ‘bridge’ between genotype and phenotype (epigenetics governs genotype and phenotype)
Epigenetic information is included in the genome of a cell but is not encoded by the DNA1,2
Epigenetic information may be inherited from precursor cells1
Epigenetic changes affect chromosome structure to alter gene expression1,2
