@TheHilaaluk asked: "if we have a wild type sequence that we wish to insert, how do we know that that particular wild type will be curative considering that wild types may differ based on ethnicity/populations? i.e. a wt sequence for one population may not be the wt for another population". Our expert's response: If there is ethnic genetic heterogeneity, and this is a totally bespoke therapy, I’d choose the WT gene from the parent (unlikely situation). If it’s not bespoke, I’d choose the sequence found at highest rates in the population with the highest amount of disease burden to insert. However, I do doubt it would really matter as many of these genes and their variance to create multiple normal ‘wild types’ are unlikely to have a significant phenotypic effect if replaced with other WTs.
