Duplication of pmp22 gene
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. A physician will look for evidence … See more CMT is caused by mutations in genes that support or produce proteins involved in the structure and function of either the peripheral nerve axon or the myelin sheath. A nerve cell communicates information to distant … See more Ongoing research on CMT includes efforts to identify more of the mutant genes and proteins that cause the various disease subtypes, discover the mechanisms of nerve degeneration … See more WebThe PMP22 gene is also involved in the majority of families with hereditary neuropathy with liability to pressure palsies (HNPP). The observation of a 1.5 Mb tandem duplication in chromosome 17p11.2, containing the PMP22 gene, in CMT1 and the reciprocal deletion in the same region in HNPP has provided a novel disease paradigm for autosomal ...
