The classification of long non-coding RNAs (lncRNAs) according to the genomic locations of Their genes.

Classification	Description
Sense lncRNAs	Transcribed from the same strand as a protein-coding gene and may overlap entirely or partially with the gene [12].
Antisense lncRNAs	Transcribed from the opposite strand of a protein-coding gene and may overlap with exons or introns [13].
Intronic lncRNAs	Located within the introns of a protein-coding gene but transcribed independently [14].
Intergenic lncRNAs	Situated between protein-coding genes and do not overlap with them. Also known as long intergenic non-coding RNAs (lincRNAs) [15].
Bidirectional lncRNAs	Transcribed in close proximity to a protein-coding gene but in the opposite direction [16].
Enhancer lncRNAs (eRNAs)	Associated with enhancer regions and may regulate the activity of enhancers, influencing gene expression [17].
