Abstract:
OBJECTIVETo explore the clinical phenotype and genotype in a Chinese family affected with early-onset familial Alzheimer's disease (EOFAD).
METHODSPotential mutation of beta-amyloid precursor protein (APP) gene, presenilin 1 (PSEN1) gene and apolipoprotein E (APOE) gene was detected with polymerase chain reaction (PCR) and direct sequencing.
RESULTSHomozygous APOE ε 2 allele and no gene mutation of APP gene were detected in the proband (III1). A 488A>G mutation (His163Arg) of the PSEN1 gene was found in the proband and other 4 family members (IV1, IV12, IV21, V2).
CONCLUSIONA mutation (c.488A>G, p.His163Arg) of PSEN1 gene was found in a Chinese family affected with EOFAD.
