The non-coding RNA gene CDKN2BAS, also known as antisense non-coding RNA in the INK4 locus (ANRIL), encodes a lncRNA regulating the expression of cyclin-dependent kinase inhibitor 2B associated with AAA development and is located within the p15/CDKN2B-p16/CDKN2A-p14 alternate reading frame (ARF) gene cluster [26,132,133,134]. The gene discussed is CDKN2B; the disease is triple-A syndrome.
