This is one of the most common things I hear, and one of the most important misconceptions to address.
For many genetic conditions, particularly autosomal recessive ones, carriers have no symptoms at all. There is no family history to notice. No warning. No pattern that would make anyone think twice.
You can carry a significant genetic variant and live your entire life without knowing, unless you test.
This is especially relevant for couples planning pregnancy in India, where carrier rates for conditions like SMA, thalassemia, and certain metabolic disorders are higher than most people realise.
Family history is one piece of the picture. It is not the whole picture.
A pre-conception genetic counseling session can help you understand what, if any, testing is relevant for your specific background and situation.
Did you know you could be a carrier without any family history? Drop your thoughts below.
