NCIt synonyms : Amphiphysin Gene; Amphiphysin (Stiff-Man Syndrome with Breast Cancer 128kDa Autoantigen) wt Allele; AMPH1;
NCIt definition : Human AMPH wild-type allele is located within 7p14-p13 and is approximately 248 kb
in length. This allele, which encodes amphiphysin protein, is involved in both clathrin-mediated
synaptic vesicle recycling and clathrin-mediated endocytosis in nerve terminals. The
AMPH gene is associated with the development of paraneoplastic syndromes such as stiff-person
syndrome.;
NCIt note : The AMPH gene produces two mRNA transcript variants via alternative splicing which,
in turn, encode distinct isoforms of the amphiphysin protein. This gene plays a putative
role in the regulation of exocytosis in both synapses and certain endocrine cell types.
The AMPH gene may also be involved in controlling the properties of the membrane-associated
cytoskeleton.;
