Chromsomes

I would say I know quite a bit about chromosomes but if you asked me to explain everything I know to you, I wouldn't know what to say. I would have a mind-blank. However, I know that I have asked a few family member and few friends to join me on this journey and follow us, as I slowly but surely update a little bit about our lives when ever I get the chance. So here I go... Im going to try and explain chromosomes in the most basic and simple form as I can before I explain Mango's chromosome anomaly (abnormality).

In every human body we have cells. Cells, are what make up our body. If we were to take one cell from our body and place it under a microscope, zoom in really close we would see that so much is happening in just ONE tiny cell. In each cell we have chromosomes. In each chromosomes we have genes. These genes tell our body what to do and how to do things. (So when our child either has a duplication or a deletion in the chromosome, the doctor's tell us how much of it is missing and added. When they tell us this - they are actually telling us which part of the gene in the chromosome that is missing)

Every person has 23 pairs of chromosomes. One copy of each chromosome from the mother and one from the father.
Mother - In a mother's 'egg' she has one copy of chromosome 1 to chromosome 22, and the 23rd chromosome being the sex chromosome, which would be an 'x' chromosome. 
Father - In a father's 'sperm' there is also only one copy of chromosome 1 to chromosome 22, and the 23rd chromosome being the sex chromosome. The sex chromosome from the father can either be an 'x'(female) or 'y'(male) chromosome. In saying this, the sex of the baby is determined from the father.

This is what two pairs of chromosomes look like (in a cartoon kinda way)


Example
Asking yourself what your looking at? I asked myself the same thing... 

Every copy of a chromosome has one short arm (p arm), a centromere and  one long arm (q arm). This means every pair of chromosomes have two short arms (p arm) and two long arms(q arm).

So, you see the dark shade of purple labeled 'P'? This is what scientist and everyone else call's the 'P arm' OR 'the short arm'. The lighter shade of purpler labeled 'q'  is either called the 'q arm' OR 'the long arm'. The yellow circle in the middle is called a 'centromere' which acts like the body part of the chromosomes holding the two arms (p arm and q arm) together. The centromere is the centre part of the chromosome but this doesn't mean it is always the centre of the chromosome when speaking about the length of it. Then there is an outline, outlining the entire chromosome which is called a 'telomere' and this keeps the entire chromosome together. 

The genes inside the chromosome are identified by using a special type of dye that defines their differences. Each part of the chromosome will be affected differently when the dye comes into contact with them. By this happening it identifies certain 'G-bands' within the chromosome which are labeled by numbers. The smallest number starting from the centromere to the largest number ending at the end of the arm furthest from the centromere. 

Something like this:
Chromo 18.org

I'm pretty sure I haven't covered all of the facts about chromosomes but I think it's most of the things that you need to know about Mango's chromosome anomaly.

Fact: In saying all that I have said. I would like to add one last thing to this short post. I found particularly interesting even though it meant nothing. Each chromosome is a certain size. The largest of the chromosome being chromosome no.1 to the smallest chromosome being chromosome no.22. 







Thanks,

Chromosome 14 and Chromosome 18

Chromosome 14 and Chromosome 18 are Mango's affected chromosomes.

There.

I said it.

Finally.

I'm not sure why I kept the chromosome numbers a secret the past year. I was mostly worried about me telling people the chromosomes involved and they would search it up on the internet the same way I did. Find all the information that I found and freak out. Like I did. I also had a small hole in my heart worried about how people would look at Mango after they knew what they did. So many other small reasons, like I was trying to protect him from the worst. I think now, I was trying to protect myself. Protect myself from opening up the wounds that haven't really healed. The wounds that probably will never really heal but only close with a thin layer of skin.

When we received the diagnosis for Mango, the geneticist couldn't have stressed more, that we should not search online. Ofcourse, that's exactly what I did as soon as we got home. I can't say exactly that it was a bad thing or a very good thing but it was definitely more good than bad. I shocked myself with all the pictures I saw and all the things I read but in time I came to accept that, that could be the worst and I would have to live with it somehow or another. Everything I read or learnt something that had something to do with Mango's chromosomes, I would share with my husband. I feel like I was trying to peel our hearts open layer by layer just to torture myself so my husband and I would stop feeling emotions. The more it hurt to read, the more times I would reread and reread what I didn't want to read anymore. In time we came to accept it all somehow, ready for everything we had learnt.

I would also like to share with you, everything I have learnt about Mango's unbalanced translocation.



P.S. Thank you from the bottom of my heart for sharing this milestone with me in opening up about Mango's chromosome numbers. It's taken more than a while to come this far and I am very glad that I have finally gotten this off my chest. Most of all, thanks for putting up with all the ranting...

Keep in touch!

Sydney has been HOT. Like extremely hot. From bushfires to strong winds blowing down trees and sweat raining from your body. Pregnancy isn't helping much when hot weather plus hot body come together, it turns out to be a disaster, my clothes have patches everywhere before I even step out of my house. I used to say I really enjoy the hot weather but now I'm starting to think that maybe, I dont like the hot so much after all.

Apart from the heat, we have been on the go non-stop. We bought a new family car (Kia sportage) and I new double pram (bugaboo donkey), which we will be getting a specialised insert for Mango to help support him. Our round of '6 month follow up appointments' have come and gone, thank god. Our paediatrician was very happy to see Mango making more noises and now weight bearing, although she thinks he may never be able to walk or talk. It has taken a while for us to get used to the fact that mango may always be non-verbal and never physically active. All is well now though. Ortho Doc gave us an all good with his feet, even though he did think that his ankle bone was a bit high still but nonetheless very nicely shaped and bones all in the right place.

Mango is growing up slowly. I feel extremely proud to be his mother and I feel the need to show him off to the world every minute of the day. He makes things so much easier to deal with because of his cheeriness and his ability to make you smile and remind you that everything isn't as bad as it always seems. There have been tough days these past few months, struggling to be ontop of everything and getting rounder everyday but mango's ability 'nothing' as the doctors like to put it, has the ability to make everything better. I have no doubt that he will conquer mountain pathways and climb hills during his journey whether it be in a wheelchair that he is being pushed around in or his on his two feet.

Everywhere we go, people fall inlove with the solider that he is. His changing people and the way they see things without even doing anything except being himself.


Sorry, I haven't been around. I hope to be back real soon!
