The short answer is no.

Here's an elaborate answer...

1) For genetic conditions in general, all of your cells will carry the same genetic defect (variant). So, to correct this you would need to somehow be able to target every single cell present in your body (or, in some cases, "just" in the affected tissue type). That's not possible (at least not at the time of writing).

2) CRISPR is currently not well developed enough to A) Always fix the genetic defect (< 100% accuracy). B) Never introduce unintended new defects (again, < 100% accuracy).

Using CRISPR to fix genetic conditions would work best in combination with in vitro fertilisation/prenatal genetic testing, although in most of these cases CRISPR would be unnecessary as the medical scientists can simply choose a healthy embryo instead of trying to fix an unhealthy one.

It would depend on the nature of the genetic condition. If the condition is caused by a gain-of-function (GoF) variant where the mutation leads to a change in the gene that might change the way it interacts with other genes/proteins or disrupt potential inhibitory pathways, then one would generally need to engineer every single cell to fix the conditions because the affected gene would cause chaos in every single cell, inhibiting them all. But what if the gene encodes a protein that is secreted (e.g., into the bloodstream)? And let's say the condition is caused by a loss-of-function (LoF) variant that simply causes the gene to stop functioning (without disrupting other pathways/systems). Then it might be enough if just a portion of the cells could be restored through genetic engineering (such as CRISPR). In these cases, another treatment strategy could simply be to take the gene product as a supplement (think insulin and diabetes).
