Duplication of pmp22 gene

WebInoue et al. (1996) suggested that since the homologous myelin protein gene PMP22 is duplicated in the majority of patients with CMT1A, PLP gene overdosage may be an important genetic abnormality in PMD and affect myelin formation. Duplication of the PLP1 gene is responsible for PMD in most patients, whereas deletion of PLP1 is infrequent. CMT1A results from a duplication of the gene on chromosome 17 that carries the instructions for producing the peripheral myelin protein-22 (PMP22). The PMP22 protein is a critical component of the myelin sheath. Overexpression of this gene causes the abnormal structure and function of the myelin sheath. … See more Charcot-Marie-Tooth disease (CMT) is one of a group of disorders that cause damage to the peripheral nerves—the nerves that transmit information and signals from the brain and spinal cord to and from the rest of … See more Diagnosing CMT Diagnosis begins with a detailed medical history, family history, and neurological examination.
