The P58 marker which defines subgroup
J1e was first identified by Karafet et al. in 2008. From early commercial testing, it appears that its associated Y-STR haplotype range spans most of the haplotypes associated with haplogroup J1, and that most members of haplogroup J1 (with the exception of some stray results) will in fact belong to this subgroup. However these are only early indications, and as of yet no systematic academic geographical testing has included this marker. One group which appears to systematically test negative for P58 are individuals with marker DYS388=13, indicating that this subset appears to be descended from a group that were negative for P58. According to Yunusbayev et al. 2006: "Overall, our results corroborate the initially suggested genetic contribution of Middle Eastern populations to Caucasus populations".
