Usher syndrome is a relatively rare genetic disorder caused by a mutation. The gene is not carried on one of the sex chromosomes (X or Y).
Turner syndrome is a chromosomal disorder.
Chromosomal, because the person with Klinefelter's would have 47 chromosomes. A genetic disorder would be any disorder having to do with genes, but would not necessarily mean having an extra chromosome.
Cri-Du-Chat Syndrome..
There are many different chromosomal abnormalities in a RETT patient it includes ring chromosome(especially X chromosome),dicentric,chromosomal and chromatid breaks etc...
Trisomy 21, Down's syndrome
Usher syndrome is inherited as an autosomal recessive trait. The term autosomal means that the mutated gene is not located on either of the chromosomes that determine a person's sex; in other words, both males and females can have the disorder and can pass along the disorder to a child. The word recessive means that to have Usher syndrome, an individual must receive a mutated form of the Usher syndrome gene from each parent. If a child has a mutation in one Usher syndrome gene but the other gene is normal, he or she is predicted to have normal vision and hearing. Individuals with a mutation in a gene that can cause an autosomal recessive disorder are called carriers, because they "carry" the gene with a mutation but show no symptoms of the disorder. If both parents are carriers of a mutated gene for Usher syndrome, they will have a one-in-four chance of having a child with Usher syndrome with each birth.
Neither. It is an extra #21 chromosome.
Down syndrome is caused by an additional chromosome while PKU is due to a mutation or defect in a gene.
Yes. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1.
It is the result of a chromosomal abnormality, in which there is an extra chromsome on the chromosome 21 pair. This is call trisomy 21.
There is no actual chromosomal change, there is an extra chromosome.
whos famous and ha usher syndrome
Turner syndrome is a chromosomal disorder.
Yes
The mode of inheritance for Turner Syndrome is recessive. Hope I helped, I have to do a project on it anyway!!
You do not "get" Down's syndrome. You are born with it. It is a chromosomal condition of the 21st chromosome.
a gene is passed on from generations and a chromosome is just found in certain cells
