Of the genes located within the deleted region, three have been proposed to be involved in cancer biology: the protein-coding gene limbic system-associated membrane protein (LSAMP) and the two non-coding RNAs LSAMP RNA antisense 3 (LSAMP-AS3) (also known as LOC285194 or TUSC7) and LSAMP RNA antisense 4 (LSAMP-AS4) (also known as BC040587)[6,12-20]. Here, LSAMP is linked to cancer.
