Genetic testing Flashcards
Best approach for single genes
Sanger sequencing
Limitations of Sanger sequencing
could lead to false negatives.
Condition may involve multiple genes
May not be involving a spelling issue (may not detect deletions or duplications)
Mutations may lie under a primer site
Time consuming
Next gen, or multi panel
example, some hearing loss disorders can involve multiple genes
Multi gene panel limitations
creates more uncertainty
“negative” does not mean that a condition is not genetic
A genotype does not always give an answer to a disorder
true
Broad term
ways to look for presence or absence of common genotypes
Exam sequencing won’t detect
Entire exome
Large del/dup
Mitochondrial genes
Trinucleotide repeats
uniparental disomy
epigenetics (methylation)
