However, a genetic variant (rs314944) just downstream of CNTNAP5 was found to be moderately negatively associated with abdominal visceral adiposity in a Korean study (P = 4.25 x 10−5), and whole blood gene expression of CNTNAP5 was reported to be reduced after bariatric surgery in patients with type 2 diabetes [19, 44]. The gene discussed is CNTNAP5; the disease is type 2 diabetes mellitus.
