Here is ours: disclaimer: This post was written by my amazing wife, and the mother of a child diagnosed with Down Syndrome! She is also a pediatrician, but not your pediatrician! All of the information on this website (although great!) is for informational purposes only. Yes, even a blog has to have fine print these days. Be sure to check out the other posts, and subscribe so you can stay updated! [This post is a part of the “ New Parent Guide To Down Syndrome” blog series. He or she simply has an extra copy of their 21st chromosome. This is a very basic overview, but hopefully helps you understand that a child born with down syndrome isn’t sick or suffering. The other way is that the baby started out as trisomy 21 and nondisjunction occurred creating cells that now contain 46 chromosomes. The baby either started with 46 chromosomes, however nondisjunction occurred with further cell division in only part of the cell lines creating some cells with three copies of the 21st chromosome. Mosaic: Not all of the cells are affected, so the baby would have cells with 46 chromosomes and also 47. Your doctor will want both parents to be tested to see if this is a possibility.ģ. This CAN be (not always) an inherited condition, which can increase your risk of having another child with Down syndrome. Therefore, even though they have the right number of chromosomes there is actually extra 21st chromosome material. Translocation: The egg or sperm have 23 chromosomes, however part of the 21st chromosome has attached itself to one of the other chromosomes during the division processes that occur when the egg or sperm were made. That egg/sperm joins with a typical egg/sperm with 23 chromosomes making a cell that has 47 chromosomes and three copies of the 21st chromosome. This creates a sperm or egg that contains 24 chromosomes with two copies of the 21st chromosome. Nondisjunction means that the cells did not equally divide the genetic information. Cells containing 46 chromosomes are split equally to create eggs and sperm, which then contain 23 chromosomes. Nondisjunction: This is the most common reason. When babies are created, they receive 23 chromosomes from their mom contained in her egg and 23 chromosomes from their dad contained in his sperm, totaling 46 chromosomes.Ĭhildren with Down syndrome are born with an extra 21st chromosome. One set of those being your sex chromosomes (X, and Y), and the others labeled 1 through 22. If you are a new parent one of your first questions may be “ What is Down syndrome?” (This by the way, was one of my husbands first questions when Noah was born.)ĭown syndrome (Trisomy 21) is a chromosomal abnormality where a child is born with three copies of the 21st chromosome (Just like in the picture!)Ĭhromosomes hold our genetic information, and there are 23 types of chromosomes. Age 3+.Not two, but three 21st chromosomes! What is Down Syndrome: Genetics The Z-Vibe is a vibration tool constructed of a durable, textured, aluminum handle and made of sturdy medical grade plastics, FDA-approved. Additional tips and spare battery sold separately (see accessories tab). Z-Vibes include special battery, one Probe Tip and one Switch Tip. The plastic Z-Vibe is more resistant to corrosion, and the colors are appealing to children. The Z-Vibe is available with either a colorful plastic or aluminum base. The Switch Tip can also be replaced with another tip in order to use two tips simultaneously. The Switch Tip at the bottom end of the handle turns the unit on and off and can be easily removed to replace the battery. The Z-Vibe has an option of using with a tip on both ends. Tips should be replaced at first sign of wear. Each tool is sealed to keep out saliva, water, or moisture. A range of tip sizes and shapes provide gentle vibrations to encourage weak muscles to start moving. Compact tips are about the size of a ball-point pen but provide a vast range of sensory stimulation. For added sensory input, use on cheeks and lips in addition to the mouth. This oral motor tool provides gentle vibrating stimulation to the child’s gums, palate, and tongue. If you're looking for oral motor stimulation or vibration for your child’s mouth, look no further than the Z-Vibe tools! Designed by a speech and language pathologist, the ARK's Z-Vibe is an oral motor tools that provides both soothing stimulation and oral sensory input, helping children challenged by eating difficulties and speech development.
