BACKGROUND:The 167K allele in the TM6SF2 gene-has been suggested to protect against cardiovascular disease at the cost of developing nonalcoholic fatty liver disease in adults.
METHODS: We performed a cross-sectional study in a population sample of 462 Caucasian children aged 6-9 y, genotyped the polymorphism using HumanCoreExome BeadChip, and assessed several cardiometabolic risk factors.
RESULTS: The 51 (11%) carriers of the 167K allele had higher plasma alanine aminotransferase (ALT) (20.8 vs. 18.4 U/l, P = 0.011) but lower plasma triglycerides (0.54 vs. 0.61 mmol/l, P = 0.024), total cholesterol (4.08 vs. 4.30 mmol/l, P = 0.016), and low-density lipoprotein (LDL) cholesterol (2.22 vs. 2.38 mmol/l, P = 0.012) than the 411 noncarriers. In factor analysis, the first factor was heavily loaded by plasma ALT (factor loading 0.63), triglycerides (-0.82), LDL cholesterol (-0.71), and waist circumference (0.61) in the carriers but not in the noncarriers.
CONCLUSIONS: The carriers of the 167K allele have higher plasma ALT but lower plasma triglycerides and total and LDL cholesterol than the noncarriers already in childhood.
