Yes.
Coincidence is not an end in itself. On the contrary, measures to minimize the probability will be permissible. Research is not patient treatment and therefore no diagnostic evaluation of the specific patient is carried out.
Since research is about generating new knowledge within a special field of interest, it is desirable to focus on specific areas, so that, for example, bioinformatic data is preferentially generated from specific areas in the genome.
Data from other areas can then be disregarded, e.g. areas in the genome where certain variants are known to have a significant impact on the subject's health. This can e.g. is done by not treating certain areas bioinformatically. One can, for example, choose to ignore the clinically relevant genes on ACMG's (American College of Medical Genetics and Genomics) list by failing to 'call' variants, or filter out all called variants, in the genes that are on the list, before further analysis.
In that case, it must be stated in the protocol that the selection takes place in such a way that no data is generated or registered regarding the unwanted information.
