Question 1

what is the difference in gene sequencing tests vs gene deletion/duplication tests?  should one type of genetic test be done before the other?

Accepted Answer

No, Wrong Issue: The issues are exactly as you have described. When a section of dna is sequenced, sometimes duplicate copies of genes are found within the dna sequence; sometimes genes usually present within the particular dna are not present, i.e. Have been deleted at some point when the dna was copied prior to whatever previous cell division.

Question 2

my brother has alpha 1 antiitrypsin gene with his liver affected,  awaiting my own results ..what are my odds of having it?  should my kids be tested?

Accepted Answer

Variable: Alpha 1 antitrypsin disease results (usually) when two unaffected carriers donate their recessive gene to the offspring. With 2 abnormal genes, the medical condition can be expressed. If you share the same parents, you have 3 potential outcomes. Normal,with two normal genes; a carrier with one normal and one abnormal: or you have it but don't know it(unlikely). 2:1 carrier than normal

Question 3

sinus infection-gene sequencing was positive for staph epidermidis mrse in my sinuses. i was started on zuvox  how serious is this infection?

Accepted Answer

MRSA sinusitis: Not uncommon, zyvox (linezolid) should take care of it, but take full prescribed dose and follow instructions, you will be fine

Question 4

if i wanted to learn about dna sequencing chemistry, bioinformatics, genetics and proteomics, what are the first topics i should research?

Accepted Answer

Molecular genetics: Learn the basics of molecular genetics first.  From there you can branch out.  Wikipedia often provides a good starting point.  A librarian at a public library can guide you too.

Question 5

the results of my pmp22 dna sequencing came back negative, but there was nuclear fluorescence noted on anti-hu antibody screen. hu western blot results were negative. what do these results mean?

Accepted Answer

: It means you should never use abbreviations in medical communications. I have no idea what PMP22DNA sequencing means. Need to know why this was ordered in order to be able to help. Best to discuss with ordering Dr.

Question 6

how much dna is needed for nanopore sequencing?

Accepted Answer

A future scientist: How much do you think is required? a single strand? A single molecule?  I encourage you to find the answer. Best of wishes to your future endeavors.

Question 7

sev. dev. delay -array comparative genetic hybridization (acgh) results indicate no abnormalities- would full genetic sequencing be advised (knome)?

Accepted Answer

Not necessarily: Newer genetic tests provide incite into a variety of issues like autism & other developmental variations.Yet causation remains elusive in many cases.Sadly, an injury to the developing brain centers from an unrecognized event in an otherwise normal  pregnancy is a likely cause for many.This occurs in at least half of cerebral palsy cases & dev.Delay could be produced in others, yet hard to prove.

Question 8

i had a pmp22 dna sequencing test sensory-motor neuropathy complete antibody panel done & i'm still waiting for the results. how long does it take to get results? i had it done on march 30th & it is now april 14th?

Accepted Answer

: Suggest that you contact the doctor's office where the test request was initiated and ask your question, as we have NO way of figuring out the timing of test results.

Question 9

hi there i am an 18 year old girl with special needs and i am struggling to find a whole exome sequencing at home website which could detect sensory processing disorder but i have read it is genetic.could you tell me a company that could detect this?

Accepted Answer

: No but I would Google it to see if gene markers fit your EXACT condition. I would start with detailed family tree of problem and discuss with Dr who knows you,

Question 10

how to differentiate between alpha thalassaemia trait and hb h disease without a genetic test?

Accepted Answer

Electrophoresis, but: Levels of hemoglobin h and hemoglobin barts should make the distinction straightforward though there may be modifying genes that could make interpretation. The real question is the implications in planning your family and for this perhaps you would like to have genetic testing done. Any hematologist would probably enjoy helping you out. Good luck.
