A 106-kb linkage disequilibrium (LD) block on chromosome 1p34, which includes the TRIT1, MYCL1, and MFSD2A genes, is associated with lung cancer prognosis and survival [1], although conflicting results of the association of this region with prognosis, in particular of the MYCL1-EcoRI polymorphism, have been reported [2,3]. Here, MFSD2A is linked to lung carcinoma.
