The Future of the NIA-LOAD Study Continuation, Funding and Reality
NIA-LOAD Study • 2002 to 2003 - 10 Centers involved • 2003 to 2004 - 8 more Centers added
Centers and Families UWStL WU Mayo 13 other ADCs IU/NCRAD CU A remarkable achievement in two years!
NIA-LOAD: Next Step Columbia Indiana Mayo (R&J) Washington Univ UWStL
Specific Aims • Complete the current collection of 1,000+ families • Identify newly affected family members and unaffected members in current families • Develop and implement standardized follow-up procedures • Ascertain a series of quantitative traits • Complete the recruitment and begin follow-up of controls • Apply to the Center for Inherited Disease Research for genotyping in the first 500 families
Aim 1 • Complete the current collection of 1,000+ families • recruitment primarily at five centers* • review of all pedigrees, standardized assessment • a regional network to travel for assessment • recruitment of ethnic minorities
Aim 2 • Identify newly affected members and evaluate appropriate unaffected in participating families • expand all pedigrees* • examine eligible family members not previously studied • re-contact family members that were unavailable or postponed
Aim 3 • Develop and implement standardized follow-up • NIA-LOAD Study quarterly newsletter for families* • create and validate follow-up data forms • develop a standardized cognitive battery for both “in person” and telephone use • continue “in person” assessments using a regional travel team • develop and implement procedures for autopsy
Aim 4 • Improve statistical power for the subsequent genetic linkage analysis by implementing procedures to ascertain a series of quantitative traits: • Age-at-onset • Cognitive performance, particularly memory • Biological markers of disease risk and progression
Aim 5 • Complete the recruitment and begin follow-up of controls: • use similar assessments as in families with Alzheimer’s disease • use similar follow-up methods • autopsy
Aim 6 • Apply to CIDR for genotyping of first 500 families: • provide all raw genotyping data in a secure, web-based format for perform genetic analyses • solicit proposals to complete basic preliminary linkage analyses which will be posted on web site available to all qualified investigators • provide genotype-phenotype information for qualified investigators
What We Will Have Produced • 500 families with familial Alzheimer’s disease • Approximately four individuals per family • Well characterized • Raw genotyping data • Basic linkage results • An additional 500 families with LOAD • 1,000 controls • All data, family structure and genotypes available to qualified investigators
Continued Role of ADC/ADRC • Leadership of this research resource • Report directly to NIA and ADC leadership • Original 18 centers will continue to be involved • Subcontracts for follow-up • Identification of new families • Subcontracts for genetic analysis in later years • Publications will be required to identify the ALL NIA-LOAD Study investigators • This is an ADC/ADRC related program
