Area of Science:

  • Genetics
  • Bioinformatics
  • Psychiatric Genetics

Background:

  • Genome-wide linkage analysis for major psychoses is time-consuming.
  • Automation can improve the speed and efficiency of this process.

Purpose of the Study:

  • To describe the Automated Linkage Preprocessor (ALP) program for analyzing genetic marker data.
  • To demonstrate the utility of ALP in linkage studies for psychiatric disorders.

Main Methods:

  • Utilized the Automated Linkage Preprocessor (ALP) program for computer analysis of fluorescently labeled microsatellite markers.
  • Employed an automated laser fluorescence (ALF) sequencer and Fragment Manager software for PCR product detection and sizing.
  • Generated genotypes suitable for direct input into linkage analysis programs.

Main Results:

  • The ALP program facilitates the detection and sizing of PCR products.
  • It effectively filters nonallele fluorescent peaks, improving genotype accuracy.
  • The system generates genotypes in a format compatible with standard linkage analysis software.

Conclusions:

  • The described automated method offers increased speed, accuracy, and cost-effectiveness for linkage analysis.
  • This approach is valuable for genetic studies of complex psychiatric disorders like manic-depressive illness.
