The NF1 gene is found on chromosome 17 and carries the instructions to create a protein called neurofibromin. Neurofibromin regulates mitosis, and works to prevent cells from growing and dividing in an uncontrolled way.

The gross profit margin ratio is a profitability ratio that basically shows us how well the company is using its assets to cover its production costs. It is calculated by subtracting total revenue from cost of goods sold and then dividing by total revenue:

It is always used together with the net profit margin because it will tell us where the company is spending the most.

If the company has a very good (high) gross profit ratio but a very low net profit ratio, it means that fixed costs are probably too high.
