glial fibrillary acidic protein[MIM*137780]
a cytoskeletal protein of 51 kD found in fibrillary astrocytes; stains for this protein are frequently used to assist in the differential diagnosis of neurologic lesions.
Farlex Partner Medical Dictionary © Farlex 2012
GFAPA gene on chromosome 17q21 that encodes a major class-III intermediate filament protein of mature astrocytes, which serves as a marker (in histopathology) to distinguish astrocytes from other glial cells, both during development and in tumour diagnostics.
Defects in GFAP are linked to Alexander disease.
