" /> Frontotemporal dementia and/or amyotrophic lateral sclerosis 7 - CISMeF





Preferred Label : Frontotemporal dementia and/or amyotrophic lateral sclerosis 7;

Symbol : FTDALS7;

CISMeF acronym : DEM; FTD3;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Frontotemporal dementia, chromosome 3-linked; Amyotrophic lateral sclerosis 17; FTD3; ALS17; Amyotrophic lateral sclerosis, chmp2b-related;

Description : A substantial minority of degenerative dementias, perhaps 10%, lack the distinctive pathologic features that allow subclassification as Alzheimer disease (see 104300) or other forms of dementia. In perhaps half of these cases of nonspecific dementia, there is a positive family history of dementia, with an apparent autosomal dominant mode of inheritance. See also frontotemporal lobe dementia (FLDEM; 600274), which maps to chromosome 17 and is caused by mutation in the microtubule-associated protein tau gene (MAPT; 157140).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the chromatin-modifying protein 2B (CHMP2B, 609512.0001);

Prefixed ID : #600795;
