==General==
*Extremely rare.
*May be related to ''[[renal medullary carcinoma]]'' which is reported to have an ALK rearrangement - t(2;10)(p23;q22).<ref name=pmid21213368>{{Cite journal  | last1 = Mariño-Enríquez | first1 = A. | last2 = Ou | first2 = WB. | last3 = Weldon | first3 = CB. | last4 = Fletcher | first4 = JA. | last5 = Pérez-Atayde | first5 = AR. | title = ALK rearrangement in sickle cell trait-associated renal medullary carcinoma. | journal = Genes Chromosomes Cancer | volume = 50 | issue = 3 | pages = 146-53 | month = Mar | year = 2011 | doi = 10.1002/gcc.20839 | PMID = 21213368 }}</ref>
