CDKN2A and neoplasm: Klorin et al. reported that LINGO2 is one of the recurrent homozygous deleted genes in malignant mesothelioma cell line and revealed that the LINGO2 gene located in the proximal region of 9p21.2 was co-deleted with the 9p21.3 region of cyclin-dependent kinase inhibitor 2A (CDKN2A)—a well-known tumor suppressor [27].
