ProFAT analysis of the expression profile of white and brown marker genes revealed that 11 brown marker genes were significantly lower (ACAA2, SLC25A20, ACO2, HADHB, ETFDH, SDHB, NDUFS1, ACADS, DLD, ETFB, PDHA1) and two white markers (ALCAM, HOXC8) were significantly higher expressed in FTO C/C obesity-risk genotype (Figure 6A, red rectangle). Here, ALCAM is linked to obesity due to melanocortin 4 receptor deficiency.
