5. Low-set ears in children
Low-set ears are a feature usually noticed at birth or early in childhood. On their own, they may not cause any problems – but they can sometimes be associated with genetic conditions such as:
– Down syndrome
– Turner syndrome
– Shprintzen-Goldberg syndrome
– Jacobsen syndrome
These conditions can come with developmental differences, unique facial or head features, or growth-related issues.
Early recognition allows parents and doctors to arrange proper medical follow-up, developmental support, and testing where needed.
6. Sticky, wet earwax
Earwax is your ear’s natural defense system – it traps dust, bacteria, and irritants and helps protect the delicate ear canal.
But the type of earwax you have can sometimes be linked to more than just ear health.
There are two main types of earwax:
– Wet, sticky earwax – more common in African and European populations
– Dry, flaky earwax – more common in Asian populations
Some studies have suggested that certain genetic traits linked to wet, sticky earwax may also be associated with a higher risk of breast cancer in women. The earwax itself isn’t dangerous – it’s more about the shared genetic markers behind it.
If you notice sudden changes in your earwax (such as much more moisture, odor, or discomfort), or if you’re worried about your personal risk factors, it’s worth discussing this with a healthcare provider.
