Well no. It's not uncommon for p-values to be even lower than that. We are talking about a specific SNP (allele) having a specific mutation being predictive of a phenotype / outcome.
So, a specific SNP mutation being predictive of a gene expression / protein is basically a p-value of 0.
Can't speak for physics experiments, but this is almost certainly not a statistical error
