What Is X-Linked Recessive Inheritance? - Charcot-Marie-Tooth Disease | Experts in CMT

X-Linked Recessive

Inheritance

One of the ways a genetic trait or disease caused by a mutated (changed) gene on the X chromosome can be passed down (inherited) from parent to child. In X-linked recessive inheritance, a daughter inherits a single mutated gene on the X chromosome from one of her parents. The X chromosome she inherits from the other parent will usually cancel the effect of the mutation, and she most likely will not have the genetic disease. If she inherits a mutated copy of the gene from both parents, she will be affected with the disease. Fathers cannot pass X-linked recessive disease to their sons. When a son inherits a mutated gene on the X chromosome from his mother, the genetic disease is more likely to occur.

A Name That Does Too Much Work

Jean-Martin Charcot's name appears throughout medicine, but nowhere does it create more confusion than in the foot. Learn why the CMT foot and Charcot neuroarthropathy, also known as Charcot foot, share a name yet differ in how they develop, appear, and are managed.


When Medicine Lost Its Compass

Evidence failed not because it was wrong, but because it was weaponized. I lived the downstream effects of that failure for more than a decade. This is what happens when medicine forgets that data always ends in a human being.


Error 404: Gene Not Found

CMT genetic testing often fails to identify the cause of the disease, even when comprehensive panels are used. Here, we discuss why this happens, what genetic tests can and cannot do, and why a negative result still matters.
