DNA testing for a basketball player?

Curry’s DNA fight with Bulls ‘bigger than sports world’

Nearly six months later, after a diagnosis of benign arrythmia sent the 22-year-old scurrying to cardiologists from coast to coast and cost him the rest of the season, Curry finds himself in a fight with Bulls management his lawyer calls “far bigger than just the sports world.”

At issue is the one-year, $5 million deal Chicago offered Curry, with this proviso: before he sets foot on the court, Curry must submit to DNA testing.

“Think about what’s at stake here,” said Alan Milstein, Curry’s attorney. “As far as DNA testing, we’re just at the beginning of that universe. Pretty soon, though, we’ll know whether someone is predisposed to cancer, alcoholism, obesity, baldness and who knows what else.

“Hand that information to an employer,” he added, “and imagine the implications. If the NBA were to get away with it, what about everyone else in this country looking for a job.”

Chicago general manager John Paxson insists the Bulls can test Curry as part of a routine physical when training camp opens next week. Milstein calls that notion “flat-out wrong,” and one already rejected by the players’ union during the last collective bargaining agreement.

“Besides, there are privacy laws on the books, both state and federal, so there’s no way they’d win,” he added. “It makes you wonder what they’re really worried about.”

Milstein isn’t the only one asking. Miami Heat forward Antoine Walker, like Curry a Chicago native, played pickup games alongside the youngster the last three weeks, and the dispute has him shaking his head.

“He looked fine, but a lot of teams seem concerned with risks nowadays. Maybe because the investments in players have become so big,” Walker said. “Maybe the Bulls want Eddy long-term, and maybe this is some kind of bargaining chip. Either way, DNA testing is taking things a little too far.”

Paxson says the team’s only motive is to learn whether Curry’s genetic makeup leaves him susceptible to cardiomyopathy, a heart condition that combined with arrythmia, could prove fatal. He said the DNA test was suggested by Barry Maron, a world-renowned specialist in hypertrophic cardiomyopathy, and complained the team’s stance is unfairly being portrayed as though “we have some other motive.

This case clearly describes the philosophical slippery slope that we now face in medicine. As we learn more about genetic predisposition to disease, we face the problem of how to use that information. If I were Curry I would want to know the answer to the DNA test. If it showed I were suspectible, then further medical care might be strongly indicated.

However, the contrast here is clear. I would personally want to know, but I agree (and I rarely agree with Milstein) that this does represent a privacy issue.

As a physician administrator, should I be able to run genetic testing on potential job applicants? Those applicants could benefit from the data, but my use of the data would likely be prejudicial.

This is not the first situation to put this issue into legal context. I know of women who refused BRAC testing, on the grounds that the results could negatively impact their insurability.

This is not a sports story, rather it is a story about the entire field of genetic testing. How we use the results, and who can demand the results will raise important issues.

Hypertropic cardiomyopathy (HCM), Mr. Curry’s suspected medical problem is an “athlete killer.” I know, because one evening it laid me out on the gym floor, my heart racing at 265 beats/minute.

“Lucky” doesn’t come close to describing my good fortune (because, obviously, I lived through it).

My heart cranked at that ridiculous pace for more than 20 minutes. In the ambulance, the EMT couldn’t slow my heart nor control my plunging blood pressure. You see, at 265 bpm, the heart doesn’t pump — it “flutters”. So fast is the beating, that no blood gets in or out. That means no oxygen reaches the brain or any other vital organ. Clots form in the heart’s ventricle and these are usually fatal.

On my ride to the ER, two of the prescribed emergency measures failed. The young fireman attending me finally administered a heavy dose of morphine and waited for me to lose consciousness so he could apply the electric-shock paddles. “It’s not a pleasant feeling,” he told me.

I never did pass out, but my life certainly passed before me. “This is it,” I calmly told myself (thanks to the morphine). But there was no mistaking my presence on the doorstep of my own finality.

Miraculously, the beating slowed and my blood pressure rose. Tears of gratitude slid from my eyes.

“I can’t belive it, dude,” the young EMT said. “Nobody’s heart beats that fast for that long — especially somebody your age.”

I’m 57.

We are just beginning to learn about the scope and deadly nature of HCM. Dr. Barry Maron is certainly the world’s expert on the subject. His medical textbook, which I’ve struggled to read, is the definitive word.

HCM is an athlete’s killer because it is responsible for the sudden death of healthy-looking young athletes who inexplicably drop dead on football fields and basketball courts. It is a genetic disorder that can take many forms. A bump of muscle inside the heart’s pumping chamber that grows and blocks the flow of blood so it can’t leave. Or a burl of gnarled, erractic muscle fiber on the heart’ surface that disrupts the normal flow of electrical pulses that control it’s pulse, causing crazy, arrythmic patterns which result in letal ventricular tachycardia. Or an ultra-slow pulse that can’t get enough blood to where it is needed.

Thanks largely to Dr. Maron, we are now aware of this once-invisible killer that claims 1-in-500. Mostly males. Usually young. Curiously, athletes. Which is why Dr. Maron is on a mission to get high schools to test their young athletes for HCM before it can claim the 1,000 or so that die “mysteriously” during organized sports every year. The cost? About $60 per test — too much in this era of tight school budgets.

But certainly not too much for Mr. Curry. He can well afford it, but probably won’t. Mostly because 22-year-olds can’t fathom their own mortality and generally consider themselves bullet-proof.

Suppose he did test positive for HCM? He’d be urged to have a defibulator implanted in his chest (which I now have)and take daily medication to regulatehis heart rhythm (which I do).

Would you opt for this at 22? I probably wouldn’t. Especially with the prospect of $5 million in the balance.

But at 57, having been so close to cashing out, you couldn’t tempt me with 10 times that amount. No doubt.

It is an awful conundrum for the Bulls’ young superstar, a player loaded with talent on the verge of a rich free agency. What would you do?

And where would he turn if he had to walk away from super-stardom because of some genetic time bomb that might suddenly explode in his chest, just when all his dreams were beginning to be fufilled? Is it worth the risk? Only he can decide.

Right now, doctors have genetic tests to identify more than 2,000 diseases — many of
which they have no cures or treatments for. If a woman tests positive for the BRAC 2 gene, her chances of breast cancer are 90%. Her sole medical option is to have both breasts removed (which some women are doing). Ask yourself: Would you want to know if you were going to get Alzheimer’s in you lifetime if modern medicine had no effective treatments or cures? Would you want to know there was a strong possibility you could drop dead at 22 in the middle of a fastbreak in front of 20,000 cheering fans?

You can understand why the Bulls want to know. You can understand why Mr. Curry might not.

But what about if your employer wants to know in order to “protect his investment”? Or your insurer? Or your mortgage company? Or your fiance?

It’s coming. Already, personal privacy rights are being overwhelmed by property rights. You and I, like Mr. Curry, are being seen more as property than individuals with rights … whether we like it or not.

A word of hope (or perhaps, solace) for Mr. Curry. I made it though a lifetime of being an athlete — college and semi-pro football, martial arts, running, body builing, dance, and stupid hell-raising — with no noticable symptoms. At age 55 in a spin class, my genetic time bomb went off. If it weren’t for the luck (or grace) of two of-duty M.D.s being in my gym lifting weights, and the close proximity of the neighborhood fire company, I wouldn’t be writing this.

Today, I sill push myself. I’m addicted to tennis … still lift weights … still spin … still eat, drink, and make merry like any normal person. Only, I have this metal hockey puck in my chest that reminds me of my mortality every single day. And every morning that I awake, I am surprised and grateful. Each moment is a diamond.

Jim,

Your story is compelling, and I’m happy that you’re alive to tell it.

The biggest problem I have with Maron’s approach, however, is that it’s much too risk-averse. It is a tragedy that people die from HCM, no question. But do the overall numbers justify preemptively diminishing the quality of life for so many people who will never develop clinical manifestations of HCM?

That’s basically Maron’s approach — the DNA test can’t tell a person when, or even IF, he’ll develop life-threatening symptoms. The test also has an enormously high false negative rate, so Maron’s advice for a teen athlete with a family history of HCM who PASSES a DNA test is the same for an athlete who’s “failed” it — stop playing, wait watchfully, and prepare for the possibility of having a pacemaker installed someday.

Eddy Curry has been cleared by a raft of world-renowned cardiologists, including Mark Estes, a member of the so-called Dream Team of cardiologists that told Reggie Lewis he’d have to retire. I find it hard to imagine that he in particular would be frivolous with this sort of diagnosis. According to the experts and to state-of-the-art tests, Curry’s heart structure and heart rhythms are perfectly normal (his heart is favorably enlarged due to high-level conditioning). There are probably few athletes anywhere in the world who’ve been tested as extensively as Curry has. Throw in the fact that there does not appear to be a family history of HCM, and I see very little real-world reason for Curry not to proceed as he has.

Again, your personal story is compelling. But if you’d had an echocardiogram in the months leading up to your rythym disturbance, your heart problem would have been detected and addressed. Curry’s quitting would be addressing a problem that doesn’t exist.

And the bigger question is this: you’ve had what appears to be a fulfilling, rewarding, active life. Do you think you would have had the same life if you took a DNA test at 22 and it came back positive for HCM? Even with an implant, your outlook may have been drastically different.

I am not at all discounting the merits of DNA testing. But the accuracy of the test, and interpreting the results, are considerably imprecise at the current time. Right now, there are no studies correlating a positive DNA test for HCM with actually developing clinical HCM, and the test itself presents false negatives at a rate ranging from 30% to 45%, and that’s in patients already exhibiting clinical HCM!

Best wishes.

Can you help me get in touch with Jim Punkre – the guy who wrote the above story who has hypertrophoc cardiomyopathy? My young son has just been diagnosed and we are struggling to cope with this news – I am looking to connect with others who have survived into middle age with this disease. Feel free to give him my email address and ask if he would drop me a note.

Thank you,

Suzanne Jarvie
