On 4/3/2018 Huffpost published an article about home genetic tests titled “Home Genetic Tests May be Riddled with Errors, and Companies Aren’t Keeping Track” written by Anna Almendrala. It’s a great title; really draws attention. But it doesn’t tell the full story of how to find out if a snp is active or not. I emailed Anna and shared this information, thinking she might tell the couple profiled in the article about it. Thanks to my beautiful friend, Ellen Asher’ guidance, I learned the key to finding out if snps are active or not is to download 23andme’ health reports to a third party DNA analysis program (I used Livewello; there are others) and click on the porphyria panel (if, of course you’re interested in finding out about what porph snps you have). That will generate a full Porphyria Panel (Jill’s was eleven pages) based on the 23andme health reports. THEN, access GWAS Central [https://www.gwascentral.org], “an extensive, centralized compilation of summary level findings from human genetic association studies, both large and small” (free). Enter the genomic location (or gene symbol, e.g. HMBS) and it will produce a report of ACTIVE snps. You can then compare the snps revealed by the 3rd party DNA analysis program to the GWAS Central print out—and voila! You’ll now know which of your snps are active.
Remember the entire genetic industry is in “hurry-up, I needed it yesterday” mode. Competition is fierce—and getting even more so. Sniping at competitor’s data is going to continue. Try to find a non-biased geneticist to review the information with you. Somebody recently posted a wonderful phrase on a FB forum: “DNA is a destiny, not a destination.” Love it! Genes set the mood, but gene expression results from a host of endogenous and exogenous factors. When it comes to your body, experience trumps experiments. Do what’s best for YOU.
If anyone wants to learn about real heroes, all one has to do is tune into closed FB porphyria forums. Tossed aside because they haven’t achieved a “real” diagnosis (as Desiree Lyon Howe articulated during the March 1, 2017 FDA/APF meeting—evidentially to her, “real” means confirmed by APF “experts”), these remarkably brave patients cope with the same challenges (debilitating symptoms but no biochemical proof) Desiree Lyon Howe was freed from at about age 27. That’s when she swallowed a Dilantin tablet (capsule?) prescribed by an unsuspecting doctor that induced a life-threatening attack which produced purple-hued urine and voila—the diagnosis of AIP which ultimately led to the establishment of the APF. One has to wonder how (or if) she would be faring today had that Dilantin never materialized and she had been left ad infinitum with symptoms as participants of these forums are. Excepting, of course, the APF members who are encouraged to “help spread the cause” by bringing these “poor souls” into the APF “light” so troll these closed forums, if not for that purpose, then to report back to the mother ship and/or bully closed forum administrators about “unfair” posts. To the real heroes on this and other closed forums, please know that your life and experiences do matter—and someday (soon, I hope) your voice will matter too. In the meantime, perhaps this article, written by another hero, Ellen Smith who suffers not with porphyria but with Ehlers-Danlos Syndrome and Sarcoidosis that may help sustain and support you through this day. http://nationalpainreport.com/living-my-new-normal-life-with-chronic-pain-that-i-dont-want-defining-me-8835779.html [Special thanks to Barbara Bradbury Wilcox for leading me to the National Pain Report forum.]
It is Rare Disease Week on Capitol Hill (2/25-3/1/2018) and I have some great news to share. In the midst of writing my 2018 FFFF white paper (this year titled STILL FEAR-RIDDEN, FRUSTRATED, FORGOTTEN AND FED-UP: Atypical Acute Porphyria Patients STILL Stuck in Urinary Diagnostic Quagmire), I was presented with some game-changing information. There is no a doubt that this information will be soundly criticized and challenged by APF et al.
Attempting to get to the truth of Jill’s AIP conundrum, I have communicated with patients, patients, doctors and specialists from around the globe since 2009. I hope you will all read 2018 FFFF in its entirety (www.purplecanaries.com) because it reveals significant information about the current (aka APF/European) acute porphyria diagnostic model. Scrutinizing enzymes is rarely, if ever considered—I know because I’ve tried. However, received a medical opinion about Jill’s case from the IVIC (Venezuela) porphyria expert team and will share its summary (some of which is in all caps—because it’s that important):
“In summary, we believe that there are enough and clear evidences: enzymatic and clinical ones to sustain a medical diagnosis of AIP regardless of the mutation identification failure, which is a known obstacle found in ~40% of populations worldwide and that the symptoms she presents and her enzyme levels are evidences of acute porphyria crises which should be treated every time, if possible with hemarginate or in its defect with hemin…Plasma PB must be performed during any acute crisis and its level should be found above any value encountered in controls if our diagnostic conclusion is right. Enzyme levels should stay abnormally low.”
“THE CRITICAL RESULT FOR A DIAGNOSIS OF AIP IS THE LEVEL OF ENZYMATIC ACTIVITY OF HYDROXYMETHYLBILANE SYNTHASE, WHETHER THE PATIENT IS PRESENTING IN ACUTE CRISIS OF IF NEVER ONE HAS OCCURRED; THE PERSON IS NONETHELESS A CARRIER OF ONE MUTATION CAPABLE OF PRODUCING AN ACUTE CRISIS. A LARGE PROPORTION OF CARRIERS (UP TO 85%) INDEED NEVER HAD ONE. IDENTIFICATION OF THE MUTATION IS AN IDEAL GOAL BUT IT IS NONMANDATORY. IN THE PRESENCE OF TYPICAL SYMPTOMS, A LOW ENZYMATIC ACTIVITY IS DIAGNOSISTIC, EVEN WITH ABSENT U-BP (read paragraph above again).”
In other words, people, unless an AIP diagnostic model includes enzyme measurement, it is incomplete, as I and others have been saying for years about US experts’ decisions to ignore the enzymatic component.
From the 1958 article “Porphyria in Africa” by A.G. Shaper, section titled “The Urine in Acute Intermittent Porphyria”: “To complicate matters, in a recent survey of 80 cases seen at the Mayo Clinic it was noted that no porphobilinogen was found in nine cases with severe CNS involvement and in six cases with abdominal crisis…It should be emphasized that porphyrin excretions may be intermittent.” Huh. Does this mean Mayo Clinc “forgot” it has this information–or disregards it to this day? I’m aware of several “undiagnosed” AIPers who will find this VERY interesting–and perhaps support their suspicions questionable responses they received from that august entity.
2018 is filled with promise.
While I’ve not been super at keeping New Year’s resolutions in the past (and in fact, stopped making them years ago), I promise this New Year will contain revolutions of sorts. In fact, Purple Canary, The Girl Who Was Allergic to School: The True Story of How School Chemicals Unleashed a “Rare” Illness that Devastated A Young Girl’s Life’s release already started the movement. Please stay with me and Jill because we will very much need your input and cooperation. It’s time for purple canaries to be uncaged.
As this very wearying year comes to an end and I find myself firmly ensconced in the 2017 holiday season, I realized that an inspiring gift had come via the Internet some weeks ago. Just words, it might seem an obscure, small thing to some, but to others, the 88 words meant someone got the message. They appeared in the September 7, 2017 transcript of an Alnylam roundtable session which featured one the foremost AIP experts in the world, Dr. Elian Sadh of Karolinska Institute in Sweden. She stated, “…As for us working in the field, there are several unmet needs and areas for improvement of this field of hepatic porphyrias. We will have very limited knowledge of this pathophysiology of the disorder as well as the natural history. And international collaborations are needed to answer this question. We need better biomarkers for the disease since ALA and PBG probably are just surrogate markers and the specific levels of porphyrin precursors do not correlate to the disease severity nor the risk for the patient to become recurrent.”
Interpretation: 1) “International collaboration are needed to answer this question”—not just Sweden, America, European or groups of other researchers working each in its own vacuum; 2) “surrogate biomarkers” (oh, like decreased PBGD seen in one of the CRIM subtypes of AIP that Jill and I (and Japanese experts) have relied on for years to predict AIP activity?); 3) “specific levels of porphyrin precursors do not correlate to the disease severity” (oh, perhaps because a) it’s a long way and a lot happens from enzyme development to urethra and no one knows exactly what quantity might become lodged in various bodily tissue (maybe most or all, leaving little or nothing to be excreted)? and b) risk for patient to become recurrent (meaning CHRONIC?). FINALLY, an expert is acknowledging that urinary biomarkers may not be the end all to be all in diagnosing AIP.
To be sure, 2018 will be an interesting year. Most of you know that Jill’s AIP diagnosis was revoked in 2014 by the director of Mount Sinai’s Genetic Laboratory. Since turning 18, her life has been pretty horrific. I wrote Purple Canary to tell the world that AIP can and does present in children. It was a brutal childhood, but adult-world porph is even worse. So with Jill’s approval, I applied for and was awarded conservatorship over her health needs. Mama JG is back. With a vengeance.
I know I’m not alone in thinking it highly inappropriate that the apf coalesced around an AIP index case who did not produce holy grail darkened urine “naturally” and then joined forces with a group to set the bar for diagnosing ALL acute porphyrias based on excretion levels of of U-PBG (which, as it turns out, is a “moving bar” because the level to secure AIP diagnosis has increased during the organization’s 35+ year history–as many can attest). A look at the numbers I reported on last week indicates that the majority of acute porph cases produced heightened U-PBG “naturally” during attack; only a handful made it into the “club” based on the administration of unsafe meds that prompted the appearance of the precious purplish urine. Refer to my FFFF paper posted on www.purplecanaries.com blog for more of this “nonsense.”
If there’s one thing that burns my biscuits and prompts me to shut that oven off it is knowing that some entity is being surreptitiously untruthful at another human being’s expense. To that end, my husband Ed and I recently exposed such deceit—by medical professionals no less. While they scramble to try (and I emphasis try) to weasel out of this one, we will proceed appropriately. It’s pretty bad when medical-related entities lie, but then again, I’m not too surprised anymore. After all, been there done that, as many of you know only too well.
