The Claim
The rs1227756-A allele in the COL13A1 gene is associated with higher baseline liver fat content, as measured by CAP score, in young Caucasian adults with normal baseline liver fat compared to GG carriers.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Young Caucasian adults with the rs1227756-A allele in the COL13A1 gene have higher liver fat levels measured by CAP score than those with the GG genotype.
See the scientific wording
In young Caucasian adults with normal baseline liver fat, the rs1227756-A allele in the COL13A1 gene is associated with higher baseline liver fat content, as measured by CAP score (234 ± 34.7 dB m⁻¹ vs. 188 ± 25.3 dB m⁻¹ for GG carriers), suggesting genetic variation may influence baseline hepatic steatosis susceptibility.
A specific gene variation causes more of a structural protein to build up around liver cells, making the tissue stiffer and less able to remove fat, so fat builds up inside the liver even without any dietary trigger.
What the research says
1 studyEven before drinking sugary drinks, people with a certain gene version had more fat in their liver than others, showing that genes can affect liver fat naturally. The study didn’t change that fact—it just added more info about what happens after drinking sugar.
