Description
The NCRAD Families sample set was genotyped at the Children’s Hospital of Philadelphia using the Illumina Infinium GSAMD-24v2-0_20024620_A1 BeadChip which captures genotype data on 759,993 genomic SNPs. These families are not evaluated in person. Family history and demographic data are collected and updated annually. Clinical information is obtained through the request for medical records which are reviewed by a central neurologist and where possible, diagnosis is determined by NINCDS-ADRDA Criteria. A standardized telephone cognitive battery is completed, where possible, every 2 years. These data are also reviewed centrally along with the medical records. Subjects are contacted annually for updates on diagnoses within their family. Brain donation is coordinated for interested participants and performed centrally. Brain tissue is available from some NCRAD Family Study participants.
