Abstract excerpt
BACKGROUND: X-linked Charcot-Marie-Tooth disease type 1 (CMTX1) is a hereditary neuropathy caused by mutations in the GJB1 gene encoding Connexin 32 (Cx32). Despite its X-linked dominant inheritance, it has been suggested that the variable phenotypic expression of the disease in females may be due to skewed X chromosome inactivation (XCI) in Schwann cells. This pilot study aimed to examine the XCI patterns in...
