Why do you think that Elam and Persia are genetically related?
All sources I have googled say that Medes/Persians were of Japhet...
ELAM
The Elam of Scripture appears to be the province lying south of Assyria and east of Persia Proper, to which Herodotus gives the name of Cissia (3:91; verse 49, etc.), and which is in part termed Susis or Susiana by the geographers (Strab. 15:3, § 12; Ptolem. 6:3, etc.). It includes a portion of the mountainous country separating between the Mesopotamian plain and the high table-land of Iran, together with a fertile and valuable low tract at the foot of the range, between it and the Tigris. The passage of Daniel (8:2) which places Shushan (Susa) in "the province of Elam," may be regarded as decisive of this identification, which is further confirmed by the frequent mention of Elymseans in this district (Strab. 11:13, § 6; 16:1, § 17; Ptolem. 6:3; Plin. H.N. 6:26, etc.), as well as by the combinations in which Elam is found in Scripture (see Gen 14:1; Isa 21:2; Ezek 32:24). It appears from Gen 10:22, that this country was originally peopled by descendants of Shem, closely allied to the Aramaeans (Syrians) and the Assyrians; and from Gen 14:1-12, it is evident that by the time of Abraham a very important power had been built up in the same region. Not only is "Chedorlaomer, king of Elam," at the head of a settled government, and able to make war at a distance of two thousand miles from his own country,

ELAM
1. Son of Shem (Gen 10:22). The name is Semitic. The Elamites gave their name to Elymais, the region on the left or E. bank of the Tigris, opposite Babylonia, between it on the W. and Persia proper on the E., and S.W. of Media. The region is also named Susiana or Susis from its capital Susa, called Shushah in Dan 8:2, where Nehemiah (Neh 1:1) waited on king Artaxerxes, and where Ahasuerus (Xerxes) held his court in Esther's (Est 1:2; 2:5) time. Daniel mentions the river Ulai near, i.e. the Greek Euloeus. From Darius Hystaspes' time to Alexander the Great it was the Persian king's court residence.
