Lab Notes

Ultimate goal: Identify genes that are trisomy-related but differentially expressed based on parent-of-origin. 1) Identify trisomic genes 2)

Methods followed for various experiments: Workflow for candidate gene identification: Start with P_PT and M_MT gene lists -> find all overlapping genes (these should represent all trisomic genes plus some noise) -> Identify genes that are up-regulated in one parent and down-regulated in another

Identified the overlapping genes with the top and bottom 10% logFC values and we are especially interested in genes that have a inverse correlations for M v P.

Fold change is First/Second, so a -FC for a PT/MT comparison means the PT is less than the MT
