13 was found to be in linkage disequilibrium with variants in two genetic regions: the long intergenic non-protein coding RNA 351 (LINC00351) and the SLIT and NTRK-Like Family Member 6 gene (SLITRK6), which have been implicated in obesity-related biological pathways and traits [16]. Here, SLITRK6 is linked to obesity due to melanocortin 4 receptor deficiency.
