What is Genetics?
Understanding Genes and DNA
Genetics is the branch of science that studies how traits and characteristics are passed from parents to their children. Every cell in our body contains DNA - a unique set of biological instructions that tells the body how to grow, function, and stay healthy. Segments of DNA called genes carry this information.
Each person has around 18,000–20,000 genes, which influence everything from eye color and height to how our body fights infections or processes food. We inherit half of our genes from our mother and half from our father, which is why families often share similar traits and health patterns.
What Are Genetic Conditions?
Sometimes, changes (also called mutations or variants) occur in genes. These changes can alter how a gene works - some are harmless, while others can cause medical conditions.
A genetic condition occurs when one or more genes don’t function as expected. These conditions can appear at birth, during childhood, or later in adulthood. Examples include thalassaemia, muscular dystrophy, cystic fibrosis, Down syndrome, metabolic disorders, and even some forms of diabetes, cancer, or heart disease.
Genetic conditions may be:
- Inherited, passed down from parents through generations, or
- New (de novo), arising for the first time in an individual.
Understanding the underlying genetic cause helps doctors make accurate diagnoses, predict the course of illness, and plan appropriate treatments or preventive measure
Why Understanding Genetics Matters
Modern medicine is increasingly guided by genetic knowledge. Through genetic testing and counselling, families can:
- Find the cause of rare or unexplained medical conditions
- Understand the risk of recurrence in future pregnancies
- Identify early or preventive treatments
- Choose the most effective medications based on their genetic makeup (pharmacogenomics)
Genetics is not just the future of healthcare - it’s the present. It empowers both doctors and families to make informed decisions, promote early diagnosis, and improve health outcomes for generations to come.
What Are Rare Diseases?
A rare disease is a health condition that affects only a small number of people compared to more common illnesses. Many rare diseases are genetic, meaning they are caused by changes in a person’s genes or chromosomes. These changes can affect how the body grows, develops, or functions.
There are over 7,000 known rare diseases, and together they affect millions of people worldwide - including many in India. Most of these conditions start early in life and can cause developmental, metabolic, or physical problems that may need lifelong care.
Because rare diseases are uncommon, they are often difficult to recognize and diagnose, leading to long periods of uncertainty for families.
Some examples include:
- Metabolic disorders (like urea cycle defects, amino acid disorders)
- Skeletal dysplasias
- Neurodevelopmental and neuromuscular disorders
- Thalassaemia and haemophilia
- Lysosomal storage disorders (like Gaucher or Pompe disease)
- Genetic forms of diabetes, obesity, or heart disease

National Policy for Rare Diseases – Government of India
The Government of India introduced the National Policy for Rare Diseases (NPRD) in 2021 to improve care and support for patients with rare conditions.
Key features of the policy include:
- Classification of rare diseases into three groups based on the type of treatment and cost involved.
- Financial assistance for selected one-time treatable conditions.
- Support for early screening, diagnosis, and research through designated Centres of Excellence across India.
- Promotion of indigenous development of medicines (orphan drugs) and diagnostic tools.
- Encouragement of crowdfunding and public-private partnerships to support high-cost treatments.
This policy represents an important step toward building awareness and improving access to care for people living with rare diseases in India.
Our Commitment
At Novagen Genetics Clinic, we aim to guide families through every stage of the rare disease journey - from diagnosis to ongoing care and support. We also help you understand available government schemes, funding options, and referral pathways for specialized treatment.
Our mission is simple:
To ensure that no patient or family feels alone when facing a rare disease - because every diagnosis deserves hope, understanding, and the right direction.
