X-Chromosome

The X Factor

The X chromosome is one of the two sex chromosomes that determine biological sex. Females have two X chromosomes in their cells, while males have one X and one Y. The X chromosome carries roughly 900 genes and represents about 5 percent of a cell’s total DNA. In CMT, the X-linked forms are caused by mutations in genes on the X chromosome, which shapes how they are inherited within families.

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.

CMT-SORD: What Is This Unique CMT Subtype?

CMT-SORD is a newly discovered CMT subtype driven by toxic sorbitol accumulation. This article explains how "SORD" works, why this subtype is different, and how it led to the fastest-moving therapeutic program in CMT history.
