What is Achondroplasia?
Before beginning to walk, a baby with achondroplasia often develops a small hump (kyphosis) on his lower back. This is due to poor muscle tone, and usually goes away after the child starts walking. Once walking, the child usually develops a markedly curved lower spine (lordosis or sway- back), and the lower legs often become bowed. The feet are generally short, broad and flat.
Achondroplasia is caused by an abnormal gene located on one of the chromosome 4 pair (humans have 23 pairs of chromosomes). In some cases, a child inheritsachondroplasia from a parent who also has the condition. If one parent has the condition and the other does not, there is a 50 percent chance that their child will be affected. If both parents have achondroplasia, there is a 50 percent chance that the child will inherit the condition, a 25 percent chance that the child will not have it, and a 25 percent chance that the child will inherit one abnormal gene from each parent and have severe skeletal abnormalities that lead to early death. A child who does not inherit the gene will be completely free of the condition, and cannot pass it on to his or her own children.In more than 80 percent of cases, however, achondroplasia is not inherited but results from a new mutation (change) that occurred in the egg or sperm cell that formed the embryo. The parents of children with achondroplasia resulting from new mutations are usually normal-sized. The gene that causes this disorder was only discovered in 1994, so much research is still being done to learn more about it. The gene is one of a family of genes that makes proteins called fibroblast growth factor receptors. Scientists have recently linked these genes with several skeletal disorders.The gene that causes this disorder was discovered in 1994, a mere 13 years ago. While scientists are eagerly studying these mutations, there is much controversy from society at the outcome of the studies.
A few notes: Intelligence is entirely normal in people with achondroplasia. The term "midget" is considered offensive in this day and age. The acceptable terms for a person with any type of dwarfism are person with dwarfism, little person, LP, and person of short stature.

The Rundown
- Each of us has 46 chromosomes, which are actually set up in pairs of two. We receive 23 from mom and 23 from dad. Twenty-two of those pairs are known as autosomes (defined for being non-sex chromosomes, which will be important to know for later). The last pair determines just that, whether we will be a male or a female and are therefore named as such, sex chromosomes. If your confused, obtain two pieces of string, thread, etc. Lay them out and cross one of the other forming an X. Loop the string lying over the top under like your making a pretzel. At this point, repeat the same step with the two strings above the swirl you already have to form a knot. You should have created something with a large knot with four appendages stemming from that knot. This is generally what a chromosome looks like, below.
- Each chromosome contains DNA, which acts as our genetic blueprint. Each DNA molecule can be composed of 10,000 to 1,000,000,000 nucleotides. Now imagine that you were to take a 0.5 mm mechanical pencil and write a repeating code over the whole chromosome you just created. Our DNA works with four repeating nucleotides (C,G,A,T), so as you write your blueprint for your chromosome keep it to four letters as that will relay all of the necessary information for the body. But remember, it is just a blueprint.
- We need a way to take our blueprint and somehow make it functional. This is known as the central dogma. Suffice it to say, several components are involved in reading the blueprint to produce a messenger RNA, which carries the information to another processing center that reads that information and ultimately makes a protein. Translation…the DNA is read (similar to the Leapfrog Tag Reading System below) and that information is then placed into, let us say, an easy bake oven. The oven produces a protein which has functional capabilities to move throughout the body and do work.
- Now, if rewind a few paragraphs and become a little more specific with the information carried by the chromosome, segments of the repeating code can be called genes, because the have a specific destination or function as to what they will be. Just think back to the blueprint, we will contain specific information for each part of the building. Each gene carries blueprints with specific instructions for making proteins. Those proteins then act as the body’s building blocks. In our case, this specific protein called FGFR3 (Fibroblast Growth Factor Receptor 3) has mutated by at least one nucleotide base. Translation…the four lettered code you put on your own homemade chromosome somehow becomes changed which means it will be read differently and ultimately will come out as something different from your easy bake oven.
- The FGFR3, from what scientists believe, becomes overactive leading to altered development of the long bones, which is what has happened in Baby W’s case.

So blessed and Welcome to Holland
by Emily Perl Kingsley, 1987, all rights reserved
I am often asked to describe the experience of raising a child with a disability - to try to help people who have not shared that unique experience to understand it, to imagine how it would feel. It's like this...
When you're going to have a baby, it's like planning a fabulous vacation trip to Italy. You buy a bunch of guidebooks and make your wonderful plans. The Coliseum. The Michelangelo, David. The gondolas of Venice. You may learn some handy phrases in Italian. It's all very exciting.
After months of eager anticipation, the day finally arrives. You pack your bags and off you go. Several hours later, the plane lands. The stewardess comes in and says, “Welcome to Holland."
"HOLLAND?!?” you say. “What do you mean, Holland? I signed up for Italy! I'm supposed to be in Italy. All my life I've dreamed of going to Italy."
But there's been a change in the flight plan. They've landed in Holland and there you must stay.
The important thing is that they haven't taken you to a horrible, disgusting, filthy place, full of pestilence, famine and disease. It's just a different place.
So you must go out and buy new guidebooks. And you must learn a whole new language. And you will meet a whole new group of people you would never have met.
It's just a different place ... After you've been there for a while and you catch your breath, you look around ... and you begin to notice that Holland has windmills ... and Holland has tulips. Holland even has Rembrandts.
But everyone you know is busy coming and going from Italy, and they're all bragging about what a wonderful time they had there. And for the rest of your life, you will say “Yes, that's where I was supposed to go. That's what I had planned."
And the pain of that will never, ever, ever go away ... because the loss of that dream is a very, very significant loss. But if you spend your life mourning the fact that you didn't get to Italy, you may never be free to enjoy the very special, very lovely things ... about Holland.
CELEBRATING HOLLAND - I'M HOME
Follow-up to the original Welcome to Holland by Emily Perl Kingsley
By Cathy Anthony
I have been in Holland for over a decade now. It has become home. I have had time to catch my breath, to settle and adjust, to accept something different than I'd planned. I reflect back on those years of past when I had first landed in Holland.
I remember clearly my shock, my fear, my anger, the pain and uncertainty. In those first few years, I tried to get back to Italy as planned, but Holland was where I was to stay. Today, I can say how far I have come on this unexpected journey. I have learned so much more. But, this too has been a journey of time.
I worked hard. I bought new guidebooks. I learned a new language and I slowly found my way around this new land. I have met others whose plans had changed like mine, and who could share my experience. We supported one another and some have become very special friends.
Some of these fellow travelers had been in Holland longer than I and were seasoned guides, assisting me along the way. Many have encouraged me. Many have taught me to open my eyes to the wonder and gifts to behold in this new land. I have discovered a community of caring. Holland wasn't so bad.
I think that Holland is used to wayward travelers like me and grew to become a land of hospitality, reaching out to welcome, to assist and to support newcomers like me in this new land. Over the years, I've wondered what life would have been like if I'd landed in Italy as planned. Would life have been easier? Would it have been as rewarding? Would I have learned some of the important lessons I hold today?
Sure, this journey has been more challenging and at times I would (and still do) stomp my feet and cry out in frustration and protest. And, yes, Holland is slower paced than Italy and less flashy than Italy, but this too has been an unexpected gift. I have learned to slow down in ways too and look closer at things, with a new appreciation for the remarkable beauty of Holland with its tulips, windmills and Rembrandts.
I have come to love Holland and call it Home.
I have become a world traveler and discovered that it doesn't matter where you land. What's more important is what you make of your journey and how you see and enjoy the very special, the very lovely, things that Holland, or any land, has to offer.
Yes, over a decade ago I landed in a place I hadn't planned. Yet I am thankful, for this destination has been richer than I could have imagined!
