Muzzey:Q:Could use 'regular' NGS? A:Yes, hardest is statistically clean calling for CNV, and enough coverage of gene +pseudogene #ASHG15
3:01pm October 7th 2015 via Hootsuite
Muzzey:Q (Lincoln) Where else could this could be used? A: Where CNV has high homology, many other pseudogenes #ASHG15
2:59pm October 7th 2015 via Hootsuite
Muzzey: From 100K samples - showed distribution of mutations in CAH. #ASHG15
2:58pm October 7th 2015 via Hootsuite
Muzzey: Seeing 93% of samples w/interchanged sequence between gene and pseudogene. Q319X + duplication 2% of pts, non-carrier #ASHG15
2:56pm October 7th 2015 via Hootsuite
Muzzey: Shows a 30kb deletion - collection of CN data, SNPs aren't informative as it is to large a region to span #ASHG15
2:54pm October 7th 2015 via Hootsuite
Muzzey: P31L mutation - shows example of carrier: CN of gene, CN of pseudogene across gene lengths, w/SNP data overlaid #ASHG15
Muzzey: Key: Use SNP and CNV data and look for mis-match. Look where CN gene vs. CN of gene at site - part of pseudogene has moved #ASHG15
2:51pm October 7th 2015 via Hootsuite
Muzzey:CYP21A1P and CYP21A2 are highly homologous; 8 of 15 sites that distinguish gene/pseudogen are deleterious. Many FN results #ASHG15

Muzzey CAH is the 7th most-common severe recessive disease; carrier rate is 1:60. Missing from 'nearly all commercial screens" #ASHG15
