Can PSD skip a generation?

Recommended Posts

m2missy    0

I found out I had PSD when I was about 12 weeks pregnant, I have read on this site that in order for it to be hereditary that you have to get it from your mother or father, that it doesnt skip generations. I had both my parents tested and they were negative, so I got tested about 8 weeks post partem, and tested deficient. So my main question is did I test to early and if so How long should I wait?

Any info would be great

Missy, you need your doctor to interpret your results based on your medical history. It is their responsibility! But if you want to form your own conclusions can I suggest you read the following page... http://www.emedicine.com/med/topic1924.htm which says "Protein S deficiency may be hereditary or acquired, the latter usually is due to hepatic diseases or a vitamin K deficiency. Protein S deficiency usually manifests clinically as venous thromboembolism (VTE). The association of protein S deficiency with arterial thrombosis appears coincidental or weak at best. Arterial thrombosis is not evident with other hereditary anticoagulant abnormalities (eg, protein C or antithrombin III deficiency, factor V Leiden gene mutation). Protein S deficiency manifests as an autosomal dominant trait; manifestations of thrombosis are observed in both heterozygous and homozygous genetic deficiencies of protein S."

Then read this page on how Autosomal Dominant Inheritance works... http://www.jewishgenetics.org/auto_dom.htm

Then read what Dr Moll says at http://www.fvleiden.org/ask/50.html and also http://www.fvleiden.org/ask/49.html where he says "Neither protein S deficiency, nor factor V Leiden "skip a generation"."

I recommend reading all of the pages I've referenced in full.

James- Thanks for taking the time to respond with all the helpful and informative

links. I have not seen a doctor who seems to know a whole lot about PSD, I plan on seeing a heamatologist (sp?) but I was hoping that mine was pregnancy acquired and that possibly I tested to early. I have no history of DVT or PE.

Thanks again,

Missy

Hi Missy,

After I lost my baby this summer, my perinatologist wanted to wait 3 months before retesting my blood to see if I still had PSD. Unfortunately, that never got to happen because I ended up in the hospital with an infected ovarian vein thrombosis and was placed on Warfarin. I'll be on it for a total of 6 months, and will be stopping it the first week of Feb. They'll retest me 4 weeks later.

It's a big difference between 3 months and 4 weeks, I know. I think the difference must be that pregnancy hormones take longer to get out of your system, and for everything to get back to normal, than it does for the Protein S levels in your body to build back up after stopping Warfarin/Coumadin.

So, what I'm trying to say is, give it more time. Perhaps wait another month or two? Have you asked your hematologist about it? Good luck.

Grace
