Down syndrome? why are they look similar to each other??

The abnormality is three copies of chromosome 21 (normally there are only two copies). This causes defects in the metabolism and morphology of the cells in the patient's body. Because it always affects the same chromosome in the same general way, the similarities have been noted.

There are SIGNIFICANTLY different degrees of severity. Some will not live very long at all (days) and others will survive 30-50 years.

you know something?.....I have to laugh every time this question comes up. children and adults with down syndrome do NOT look alike!!!!!..some of the facial characteristics of down syndrome are: almond shaped upward slanting eyes, broader nose, ears that are lower on the head, larger tongue, smaller pallet brushfield spots in the eyes (makes their eyes sparkle) etc. each individual is different...some may have all of the characteristics of DS, while others may only have one or two they are as varied as you and I and they do inherit features from their parents as all human beings do.

I think why so many people believe they all look similar is because they notice the common characteristics of the "syndrome" and don't know how to look past it, or want to look past it...they are different from "typical" society so they are labeled.

As for facial paralysis? (stated by someone else's answer)OMG that is a bunch of crap....and no they are not related.

those with Down's syndrome probable do no longer all look alike to those that know them in my view. There are, even nevertheless, actual characteristics that they have in basic. Down's syndrome is a genetic disease that replaced into customary on the 2d of concept. commonly, there are 23 pairs of chromosomes that make up the fertilized egg. considered one of each pair is from the sperm and the different from the egg. In Down's there is an extra chromosome 21. The medical term is trisomy 21. it truly is the common clarification for Down's syndrome. the main obtrusive consequenses of having an extra chromosome 21 are an epicanthal fold around the eyes, short stature, dental deformaties, vast chest and psychological retardation. The epicanthal fold related to the eyes provide them an Asiatic or Mongoloian visual charm, as a result, the older term mongoloid. As in any group of people, those with Down's reveal distinctive personalities and dissimilar know-how. by using fact they look distinctive, some people might tease or bully individuals who've Down syndrome. yet those people have thoughts purely like each physique else. while they get teased, it hurts their thoughts. they go with to be favourite and have acquaintances. in case you recognize somebody with Down syndrome, you could be a huge help by ability of no longer teasing him or her. particularly, furnish a helping hand and a delightful notice of encouragement.

It is the chromosomal abnormalities that make them look alike. They all have the same problem with the same chromosome, so of course they look alike. No, they aren't all related. But the same facial features are there because of the problem.

I have a son who has DS sometimes I see the characteristics that others see. The flat bridge nose,slanting eyes, small ears all of that. It isn't know yet why they have some of the characteristics of others with DS.

Well, of course all Down's patients aren't related. Don't be silly. This will explain:
