EFHC2 nalazi se na negativnom lancu (čulni lanac) X hromosoma na poziciji p11.3. To je jedan od nekoliko odabranih gena sa dokazima in vitro, koji sugeriraju da mogućnos izbjegavanja inaktivacije X-a.^[6] EFHC2 obuhvata 195.796 baznih parova i susjed je gena NDP koji kodira protein Norriejeve bolesti. Preliminarni dokazi zasnovani na studijama povezanosti genoma našli su vezu sa SNP u intronu između egzona 13 i 14 iz EFHC2 sa izbjegavanjem oštećenja.^[7]

Transkript iRNK koji kodira protein EFHC2 ima 3.269 baznih parova. Prvih devedeset parova čine pet osnovnih neprevedenih regija, a posljednjih 1.913 baznih parova čine tri osnovne neprevedene regije.

Gen EFHC2 kodira protein od 749 aminokiselina, koji sadrži tri DM10 domene (InterPro: IPR006602 IPR006602) i tri motiva za vevanje kalcija EF-šake.^[5] Procijenjeno je da izoelektrična tačka EFHC2 kod ljudi iznosi 7,13.^[8] U odnosu na druge proteine u ljudi, EFHC2 ima manje alaninskih i veći broj tirozinskih ostataka i predviđa se da se nalazi u citoplazmi.^[9]^[10]

EFHC2 je široko izražen u centralnom nervnom sistemu, kao i u perifernim tkivima .^[11]

Srodni protein, EFHC1 kodiran je genom na hromosomu 6. Pretpostavlja se da su oba proteina uključena u razvoj epilepsije^[12]^[13] te da ovaj gen može biti povezan s prepoznavanjem straha kod osoba s Turnerovim sindromom.^[5] Mutacija u EFHC2 koja rezultira supstitucijom serina u tirozin na aminokiselinskom položaju 430 (S430Y) povezana je sa juvenilnom mioklonskom epilepsijom u njemačkom muškom stanovništvu.^[12] Pored toga, jednonukleotidni polimorfizam u EFHC2 korelira sa smanjenom sposobnošću pacijenata sa Turnerovim sindromom da prepoznaju strah u izrazu lica ;^[14] međutim, ovi nalazi ostaju kontroverzni.^[15]
