Genetics – Understanding, Testing, and Managing Hereditary Risks in Parenthood

Overview

Genetics plays a vital role in shaping every pregnancy. Each child inherits genes from both parents, and in some cases, these genes may carry a risk of inherited conditions. Understanding these risks early allows couples to make informed decisions and plan a safer path to parenthood.

At Milann Fertility & Birthing Hospital, genetic counselling and testing help identify potential hereditary conditions, assess risks, and guide couples toward safe and informed reproductive choices.

What is Genetic Counselling and Testing?

Genetic counselling is a consultation that helps individuals or couples understand their risk of passing genetic conditions to their children. Genetic testing involves analyzing DNA to detect gene mutations or chromosomal abnormalities that may affect fertility, conception, or the health of a future baby.

Types of Genetic Disorders

• Single-gene disorders: Caused by mutation in one gene (e.g., cystic fibrosis, sickle cell anemia)
• Chromosomal disorders: Caused by abnormal chromosomes (e.g., Down syndrome, Turner syndrome)
• Multifactorial disorders: Combination of genetic and environmental factors
• Mitochondrial disorders: Passed from mother through mitochondrial DNA

Why is Genetic Testing Done?

• Risk Identification: Helps detect hereditary disorders before conception
• Informed Decisions: Supports better reproductive planning
• Prevention: Reduces risk of passing severe genetic conditions
• Treatment Planning: Guides appropriate fertility treatments

Who Can Pass Genetic Disorders?

• Both Parents: Can carry and pass genetic mutations
• Inheritance Pattern: Some conditions come from either parent
• Maternal Only: Mitochondrial disorders pass from mother
• Random Cases: Some chromosomal abnormalities occur spontaneously

Preparation for Genetic Testing

• Medical History: Provide family and health background
• Pregnancy History: Discuss miscarriages or complications
• Sample Collection: Blood or saliva samples required

Process of Genetic Testing

1. Pre-Test Counselling: Understand purpose, benefits, and limitations of testing
2. Sample Collection: Blood or saliva samples from one or both partners
3. Laboratory Analysis: DNA tested using advanced techniques like sequencing
4. Post-Test Counselling: Results explained with guidance on next steps

Based on the results, doctors may recommend further treatment options such as IVF with genetic testing or other assisted reproductive techniques.
