A recently published population study of 867 adolescents from the United States of America included in the National Health and Nutrition Examination Survey 2017–2018 found even more alarming data assessing the prevalence of NAFLD with transient elastography: 24.2% of all participants had any degree of steatosis, and 4.4% of them had significant liver fibrosis not associated with either overweight/obesity nor ALT level, but the findings were not confirmed or further analyzed by liver biopsy [25]. This evidence concerns the gene GPT and Hepatic fibrosis.
