It’s not frequent, however it’s potential to move Down syndrome from father or mother to little one. Generally, a father or mother has what specialists name “translocated” genes. Which means a few of their genes aren’t of their regular place, maybe on a unique chromosome from the place they’d normally be discovered.
The father or mother doesn’t have Down syndrome as a result of they’ve the suitable variety of genes, however their little one might have what’s referred to as “translocation Down syndrome.” Not everybody with translocation Down syndrome will get it from their mother and father — it might additionally occur by likelihood.
Forms of Down Syndrome
There are three kinds of Down syndrome:
- Trisomy 21. That is by far the most typical kind, the place each cell within the physique has three copies of chromosome 21 as an alternative of two.
- Translocation Down syndrome. On this kind, every cell has a part of an additional chromosome 21, or a completely further one. However it’s connected to a different chromosome as an alternative of being by itself.
- Mosaic Down syndrome. That is the rarest kind, the place just some cells have an additional chromosome 21.
You may’t inform what kind of Down syndrome somebody has simply by how they appear. The results of all three varieties are very related, however somebody with mosaic Down syndrome might not have as many signs as a result of fewer cells have the additional chromosome.
Down Syndrome Analysis

- Percutaneous umbilical blood sampling (PUBS). That is additionally performed within the second trimester utilizing blood faraway from the umbilical wire.
