In a family with unusually low cholesterol levels, scientists found a unique genetic clue. This family had a rare gene variant that might explain their condition. The variant is in a gene called ANGPTL3. This gene is not often linked to low cholesterol, making this discovery quite interesting.

Researchers wanted to understand if this variant was indeed causing the low cholesterol levels. They studied the variant in detail to see how it worked. The variant is called p. H343R. It is a type of change in the gene that might affect how the protein works.

The family's low cholesterol is a condition known as hypobetalipoproteinemia (HBL). Usually, HBL is caused by multiple genes or a single gene called APOB. The ANGPTL3 gene is rarely the culprit. This makes the family's case quite special.

The researchers are still figuring out if the p. H343R variant is the main reason for the family's low cholesterol. They are also looking at how other genes might be playing a role. This study could help understand more about how genes affect cholesterol levels.

Understanding this genetic puzzle is important. It could lead to better ways to manage cholesterol levels in the future. The family's unique genetic makeup offers a rare glimpse into the complex world of genetics and health.
