Know your variants.
Tune your life.

In my early 40s, I started hearing a high-pitched ringing that wouldn't go away. I later learned it was tinnitus. It was hard - hard enough that I needed a psychologist's help just to cope with it in those first months.

Once I'd learned to live with it, I wanted to understand where it actually came from. I took a Tunio Exome test, and that's when I found it: a rare variant in the DSPP gene - linked to progressive hearing decline and high-pitched sound sensitivity.

It didn't undo the tinnitus. But finally understanding why gave me something I hadn't had before - an answer.

In my late 30s, I started paying closer attention to cancer news. I'll be honest - cancer is something I've always been afraid of. With breast cancer in my family, I wanted real answers about whether I carry a BRCA1 or BRCA2 variant.

I ordered a Tunio Exome test to find out. Fortunately, I don't carry the high-risk variant - and that's a relief I don't take for granted.

Colon cancer has touched my family more than once, and for a while that made me anxious every time I thought about it. I decided I'd rather have real answers than just worry.

I took a Tunio Exome test to check for variants linked to Lynch syndrome, one of the more common inherited causes of colon cancer risk. It's not something tied to one gender - anyone can carry it, and anyone can pass it on.

My results came back clear of the known high-risk variants. It didn't erase my family's history, but it gave me something steadier to stand on - information instead of just fear.

I've run six marathons, and in nearly every one I've hit the same wall around the 29km mark - pace falls apart even when the training block went well and fueling was dialed in.

I took a Tunio Genome test to obtain gene data on what works for me to maintain and improve my performance. I carry an MCT1 variant linked to slower lactate clearance, which tracked with exactly what my watch data had been showing for two years. It helped explain why my easy long runs always felt fine, but my legs gave out faster than my fitness numbers said they should once I pushed into race pace.

I'd tried every diet that was supposed to work and nothing stuck long-term. I took a Tunio Exome test mostly out of curiosity about my HbA1c creeping up every year at my physical.

I carry a TCF7L2 variant linked to reduced insulin response, plus an FTO variant tied to a stronger hunger signal after meals. Neither one was an excuse, but it explained why portion control alone was always such a fight for me. I shifted to a lower-glycemic, higher-protein pattern instead of just eating less, and my next HbA1c came back down for the first time in years.

I'd been on a vitamin D supplement for two years and my levels barely moved. A Tunio Exome test showed variants in GC and CYP2R1, the genes that affect how your body processes and circulates vitamin D in the first place - so a "normal" dose wasn't doing what it would for most people.

I also carry a PER3 variant linked to a later chronotype, which matched something I'd suspected for years: I was fighting my own body clock trying to sleep on an early schedule. Between a higher vitamin D dose and shifting my sleep window later instead of forcing it earlier, I'm finally waking up rested.
