* The labs that did traditional PGT-M available to us wanted embryo biopsy, parent samples, grandparent sample. The PGT-WGS guys wanted embryo biopsy, parent sample. For reasons specific to us, grandparent samples were not easy - and I found the reason for not requiring it convincing.
* I preferred moving from the biology space to the data space because:
* * At the time, only some 25 years had passed between the association of the variant with hearing loss and our attempt. There was a reasonable possibility our last child would be 5 years out from there, depending on implantation success, needing to go to surrogates, etc. That's a fifth of the way again from original discovery. It's entirely possible that new associations are found in that period.
* * I am a bad biologist, but I have a degree in Mathematics and I would say I'm a competent programmer. I should be able to stitch together a minimal bioinformatics pipeline, if required, with the assistance of my cousins (two of whom have Ph.D.s in Molecular Biology).
* I trusted the WGS process more because of greater effective transparency. At the end of the process, I requested and obtained the FASTQs for our embryos. This is far superior to receiving a Detected / Not Detected result.
