Question 1

what is xyy syndrome or disease?

Accepted Answer

Extra Y chromosome: About one man in 1000 has an extra Y chromosome and it's likely to be discovered only if there's some investigation because of some problem such as autism. This has given rise to the myth that autism, criminal behavior and so forth are more common in such men. They average taller and tend to get worse acne. The "criminal" claims haven't held up to real science.

Question 2

what exactly is xyy syndrome or disease?

Accepted Answer

Usually non-problem: This is a man with an extra y chromosome. These men tend to be tall and to have more troubles with acne than others. A junk-science paper and a false claim by murderer richard speck popularized the myth that these men tend to criminality. If there are no health problems, xyy almost never gets discovered except by prenatal screening; in the latter case it usually causes no troubles.

Question 3

i was wondering what is xyy syndrome or disease?

Accepted Answer

Aneuploidy: 47, xyy syndrome is a sex chromosome numeric abnormality or aneuploidy. Normally the cells of the body, barring sperm and egg, contain 22 pairs of somatic chromosomes and one pair of sex chromosomes (xx=girl, xy=boy) for a total of 46 chromosomes. Boys with an extra y are usually tall and may have learning disabilities and behavioral problems due to poor judgment/lower mean iq.

Question 4

can you help me find me a pedigree for a male who has 47, xyy syndrome (xyy syndrome)?

Accepted Answer

No: There is no such thing as a "pedigree" for xyy. This is a sporadic event and won't be reflected in the rest of the family, either his parents or his children. Learning the fundamental concepts of genetics is subtle. While other chromosomal anomalies (microdeletions, robertsonian and other translocations) can produce typical family trees, xyy won't -- it can't be passed on.

Question 5

is there a particular chromosome xyy syndrome is located? and is it recessive or dominant?

Accepted Answer

No: XYY syndrome is neither autosomal dominant or recessive.  See a geneticist about inheritance patterns.  It is often causes by chromosome nondysjunction (lack of separation).  There is not a particular chromosome but the  sex chromosomes are called X and Y.  Females typically are XX and Males XY.  XYY is causes by a Y chromosome separation issue.  XYY individuals are usually normal males

Question 6

is xyy syndrome-                                 
sex-linked-yes or no; particular chromosome; recessive or dominant?

Accepted Answer

Klinefelter Syndrome: Hi,

Klinefelter Syndrome, or XYY syndrome is a syndrome where males have an extra Y chromosome, which makes them 47 XYY rather than 46 XY.

It is not a sex-linked, autosomal dominant, nor autosomal recessive disorder.

The inclusion of the extra Y chromosome is thought to be a random event, even in cases of 47 XYY mosaicism.

Question 7

does the asperger syndrome have xyy chromosome?

Accepted Answer

Asperger's disorder: There is no consistent chromosomal abnormality associated with asperger's disorder, either for males or females.

Question 8

how is a diagnosis of sjgren's syndrome made?

Accepted Answer

2 ways: One option is to have dry eyes, dry mouth, a positive ANA and a positive ss-a or ss-b antibody.  The second option is to have a minor salivary gland biopsy with typical inflammation instead of the ss-a or  ss-b antibody.

Question 9

can you tell me if xyy syndrome is sex-linked or autosomal?

Accepted Answer

Neither: It is a karyotype disorder. The x and y chromosomes are sex chromosomes, but the disorders of chromosomes themselves (aneupolidies, translocations, etc.) are not the classic mendelian disorders that we discuss with respect to "sex-linked" and "autosomal.".

Question 10

who makes rett syndrome diagnosis?

Accepted Answer

Pediatrician: A good experienced pediatrician can make the diagnosis, especially if they have other patients with rett's.
