Charcot-Marie-Tooth disease type 2

MedGen UID:: 124378
•Concept ID:: C0270914
•: Disease or Syndrome

Synonyms:	Charcot-Marie-Tooth Neuropathy Type 2; Charcot-Marie-Tooth, Type 2
SNOMED CT:	Charcot-Marie-Tooth disease, type II (398187000); Inherited neuronal peroneal muscular atrophy (398187000); Hereditary motor and sensory neuropathy type II (398187000); Peroneal muscular atrophy of neuronal type (398187000); Charcot Marie Tooth disease, type 2 (398187000)
Modes of inheritance:	Autosomal dominant inheritance MedGen UID: 141047 •Concept ID: C0443147 • Intellectual Product Source: Orphanet A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele. Autosomal dominant inheritance (Orphanet)

Genes (locations): Gene(s) directly associated with this condition or phenotype.	DNAJB2 (2q35); IGHMBP2 (11q13.3); MARS1 (12q13.3); MME (3q25.2)
Related genes: Gene(s) associated with related conditions. For conditions in a hierarchy, the parent condition will list the genes associated with the children conditions.	TRPV4, JPH1, GDAP1, HSPB8, KIF1B, MFN2, RAB7A, NEFL, MPZ, HSPB1, GARS1, DYNC1H1, AARS1
