Definition
GOF
Term
What is the mutation type for Fragile X Syndrome?
Definition
LOF Fragile site
Term
? ? 2 homologous genes both will not always be expressed.
Definition
Genomic imprinting
Term
Genome imprinting is ? specific
Definition
gender
Term
The more ? of a gene the greater the chance of it determining what will happen.
Definition
copies
Term
Higher frequency of mental retardation in fragile X occurs in ?
Definition
males
Term
What can be described as follows
majority are midlife occurring in either gender parent
Definition
Huntington's disease
Term
What can be described as follows

the onset of phenotype is one of movement disorder in terms of trembling of a body part (limb hand) and goes to other body partsDeath about 15 years after diagnose a lot of uncontrollable movement and in the end they are curled up in bed totally dependent on other people central nervous system deteriorates Early on they have fits of rage
Definition
Huntington's disease
Term
What is the easiest test to do for Huntington's disease?
Definition
Southern blotting test
Term
What can be described as follows?
pheno they eat excessively at early age, obesity hyperphasia, cognititve disability
Definition
Prader Willi Syndrome
Term
For Prader Willi Syndrome if you had 3 of the 15 gene = trisomy they will die another mutation converts one trisomy to disomy resulting in uniparental disomy 2nd route due to nondisjunction

3rd way is due to mutations in what?
Definition
imprinting in genes that govern methylation fail to methylate only 5% of the time does this occur
Term
In Angelman syndrom if you have silencing of father then you can have what?
Definition
uniparental disomy
Term
You can have mutation of mother's Angelman syndrome region which accounts for ?
Definition
60 to 70%
Term
What disease can be described as follows?
is a rare genetic disorder in which seven genes (or some subset thereof) on chromosome 15 (q 11-13) are deleted or unexpressed (chromosome 15q partial deletion) on the paternal chromosome.
For the genes affected in PWS, it is the paternal copy that is usually expressed, while the maternal copy is silenced. This means that while most people have a single working copy of these genes, people with this will have no working copy
Definition
Prader Willi Syndrome
Term
PWS has the sister syndrome ? in which maternally derived genetic material is affected in the same genetic region.
Definition
Angelman syndrome
