Final answer:
Antiphospholipid syndrome (APS) is an autoimmune disorder that involves the immune system mistakenly attacking certain proteins in the body. While there are certain genetic factors that can increase the risk of developing APS, it is not solely caused by a mutation on a specific gene.
Step-by-step explanation:
Antiphospholipid syndrome (APS) is not primarily caused by a mutation on a specific gene. APS is an autoimmune disorder where the immune system mistakenly attacks certain proteins called phospholipids in the body, leading to blood clotting problems.
While there are certain genetic factors that can increase the risk of developing APS, such as variations in the apolipoprotein E (APOE) gene, it is not solely a result of a single gene mutation.
