Week 1: New Genomics Flashcards
Karyotype Resolution
5 Mb
FISH Resolution
40-250 kb
Microarray (aCGH)
30 kb
aCGH is 1st line test for:
- Multiple anomalies but no well-defined syndrome 2. Apparently non-syndromic DD/ID 3. ASD
CMA Limitations
No balanced rearrangements, no low-level mosaics, no information on structural nature
SNP array can detect
CNVs, ROH, UPD
WES Detection Rate
25-50%
WES Limitations
Limited detection of CNVs/trinucleotide repeats, not all exons, not all exons well-covered, doesn’t look in regulatory/untranslated regions
WES ‘major’ ‘risk’
Incidental findings
Must report incidental findings, regardless of age or desire if
