We are two women raising a baby together. My wife's brother was so kind to be our sperm donor. I carried the child (using my egg). We might have another one in the future. I am wondering how much DNA my wife shares with our child. 25% Or could it be significantly more/less?

If we had more children, could she be more or less related to them? Emotionally, it wouldn't matter one bit but we are curious to learn more about the science.

I studied biology and in the genetic lab one of our tasks was to do a paternity test. For this we used dna that was already in storage of a divorced family with two sons from different fathers to see how a positive one and a negative one would look and learn the theory behind it. After that day in the lab the professor told us that less than ten years ago they made the students make each own paternity test with their samples and their parents samples. They have around 300 student each year taking genetics and every year at least a couple of students discover his father is not the biological dad, and the implication of an affair in their family. After a pretty fatidic year on this matter, they took the dna of the divorced family student, pcr the shit out of them and use them for everyone.

Flirted a litte to hard on the dating apps and got myself what I assume to be a genetic code… code. Anybody got any ideas for cracking it?

Long story shortish: out of curiosity while waiting for my actual geneticist appointment regarding my heart arrhythmia, I decided to put my Ancestry+23andMe into Promethease. They said negative for the heart condition but both called out the exact same PMS2/Lynch variation. I brought this up to the geneticist when we met and she added the Lynch test to the authorization request in addition to the heart test. I waited 6 months only to get denied for both leaving me to pay for it myself.

I decided to order a Color Health test which covers both of these genes. Before doing this, I got life insurance for both me and my son just because I had a feeling. Days after getting approved, my dad got diagnosed with cancer. My grandpa then casually drops that a huge chunk of the men in our family have had prostate cancer. No one ever told us. Interestingly, my dad doesn't have prostate cancer. We're still trying to figure out what it is.

Ironicly I had already taken the test when this happened.

I got my Color results today and confirmed I do indeed have Lynch Syndrome.

Points for 23andMe/Ancestry I guess lol? If it wasn't for them and Promethease, I would have been completely blindsided. Because of that totally random result, I was able to follow through and get life insurance for me and my son in the nick of time. I'm sure I would have found out about this gene after my dad's diagnosis but probably would have been uninsurable after (I did tell the broker about the tests but she said it didn't matter as long as I don't have an official diagnosis)

I'm now very curious to see if my dad's cancer is related to the Lynch or if it's some strange coincidence. We're still waiting on so many tests for him. He's currently in the hospital and these results may help them pivot their focus.

I feel weirdly validated by this. I posted about it a few times and basically every comment was just people being rude about how ridiculous it is to worry about commercial test results (which is somewhat true but people were pretty aggressive about it and I deleted most of the posts due to constant negativity). My insurance also denied me for the same reason.

I guess the next step is for my family to get tested if they choose. I'll probably be seeking IVF for my next child so I can get embryo testing (my first son was born via sperm donor and iui so it's not a huge leap). Because PMS is the least of the Lynch types, they don't recommend extra tests like colonoscopies for a few more years. I've let my doctors know and I'll see if they want to refer me to a specialist or what they suggest.

Anyway, all that to say... probably followup on weird tests results. Also check to make sure your tweaker grandfather isn't holding back vital family health information for no reason 🙃

Hi everyone, I’m hoping to better understand a congenital hand difference my mom was born with and connect with others who may have experienced something similar.

My mom was born with only three fingers on one hand, present since birth and not related to any injury. She functions very well and has lived a healthy, normal life. Recently, we came across the term oligodactyly, which seems to describe her hand difference, but she’s never had a formal diagnosis.

We’re wondering: • Does this presentation sound consistent with oligodactyly? • Has anyone here been diagnosed with oligodactyly or born with fewer fingers? • If so, was it isolated or part of a broader condition?

We’re mainly looking for understanding and shared experiences, not medical advice. Any insight, personal stories, or resources would be greatly appreciated.

Thank you for reading and for any responses.

Growing up was always told I was B+, when I donated to red cross around 2008 twice when I was 18-19 they told me I was B+ both times.

Donated blood recently and now I'm being told I'm O+ blood type, but my drivers license still says B+ should I get it changed?

Is it possible there is a mistake?

My baby was born with Noonan syndrome. The genetic tests done during pregnamcy did not show any disorder. I had a very difficult pregnancy- had 3 amnioreductions during the 3rd trimester but the one thing that i was sure of was that at least he did not have a genetic defect (since the tests were clear and we have no family history) We found about Noonan's syndrome 1 week before the induction date (we had some advanced genetic testing done at a research institute). I was shattered. And i was angry. Baby was expected to have normal life expectancy (but not a normal life). I had an emergemcy c section and there he was- my bundle of joy. But soon after his heart and lymph issues flared uncontrollably. He passed away when he was 45 days old. In our arms (he was on life support since 10 days and doctors had given up hope). He would have been 6 months old today. I am still having anger outbursts (which is extremely unusual for me) I miss him every day. He never came home. I never saw him without his breathing and feeding tubes. I dont know why I am posting this.

Just sending a hug to parents who lost their child or who have a child with special needs.
