This finding is consistent with the results from Andreasen and co-workers, who in a study comprising 18,014 Danish participants found that the CTNNBL1 rs6013029 T-allele and the rs6020846 G-allele confer an increased risk of developing obesity, especially morbid obesity [30]. Here, CTNNBL1 is linked to obesity due to melanocortin 4 receptor deficiency.
