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

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

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.". ...Read more

Is angelmans syndrome sex linked?

Is angelmans syndrome sex linked?

No: This is a classic homework question and an important idea. If a child does not have a good copy of ubd3a from mom, the child gets angelman's. If a child does not have a good copy of ubd3a from dad, the child gets prader-willi. This is imprinting and is a subtle concept, unlike the easier idea of sex-linked inheritance. ...Read more

Is down syndrome autosomal or sex linked?

Is down syndrome autosomal or sex linked?

None of the above: Down syndrome happens when an extra 21 chromosome is present in all the cells of the body. It happens before conception when the donor egg fails to shed one of its 21 chromosomes in the formation of the egg; the male 21 joins the female pair & creates an embryo with 3 number 21's. It has nothing to do with traits or mutations in the gene code. ...Read more

Does tms (traumatic masturbatory syndrome) affect sex?

Does tms (traumatic masturbatory syndrome) affect sex?

Pop diagnosis: I've run into a "pop" claim that if a man usually masturbates lying face-down, he won't be able to have intercourse normally (tms!). This sounds like dubious fear-mongering / tabloid stuff and I have seen nothing in the real medical literature. A problem exists only if you can't function and you have a really meaningful and warm relationship with the other person. Good luck. ...Read more

Is edward's syndrome autosomal or sex-linked? Dominant or recessive?

Is edward's syndrome autosomal or sex-linked? Dominant or recessive?

None of the above: Edward syndrome is brought on by an abnormality of chromosome numbers, specifically an extra 18. The abnormal egg with a single chromosome 1-17 & 19-22 + x has a pair of 18's. When the sperm brings a single chromosome 1-22 + x or y then the embryo ends up with 47 chromosomes rather than 46 in every cell.(3-18's) the excess distorts the organ building information & defects arise. ...Read more

Is XYY syndrome- Sex-linked-yes or no; particular chromosome; recessive or dominant?

Is XYY syndrome- Sex-linked-yes or no; particular chromosome; recessive or dominant?

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.

Is Down Syndrome a sex linked chromosomal disease?

Is Down Syndrome a sex linked chromosomal disease?

No: Down syndrome is an abnormality of chromosome numbers, not a mutation on a sex chromosome. During conception only one of chromosome of each pair is given by both parents to the fertile egg. If a parent adds their 2 # 21 chm to the other parents # 21, 3 end up in the egg ; the excess 21 causes the all the problems. Rare forms are causes by an extra piece of a 21, but that's another issue. ...Read more

Any link between aspergers syndrome & hypothalamus dysfunction?

Any link between aspergers syndrome & hypothalamus dysfunction?

Maybe: There were news media reports in the mid 2000s regarding oxytocin & aspergers. The latest definitive article I found, from mit & published 2010, indicated the lower amounts of oxytocin produced could be implicated in social awkwardness of neuropsychiatric disorders. But did not have a cause & effect relationship. The hypothalamus is the last common neural pathway for social interaction in mammals. ...Read more

Is there any link at all between schizophrenia and aspergers syndrome? Are the two related in any way, shape or form?

New perspective...: Research has shown that a significant number of people previously diagnosed with schizophrenia are being re-diagnosed with autism spectrum disorders (ASD), to include Asperger's.

Can there be any sort of link between Asperger syndrome and stuttering?

Not really: The diagnosis of aspergers dis specifically excludes language problems. The diagnoses are seldom used perfectly as intended, and they are changing this year to broaden the autism disorders to one broader category. Stuttering is not a common language problem in autism spectrum disorders however. Other language issues more typical, but over;lap can surely occur. ...Read more
