RT copy number as a function of gene length. RTs consisted of all repeat masked elements, only L1, or only Alu. Gene length was calculated as transcription start to transcription stop. The element count was normalized by the total number of elements across all genes. Genes were then subdivided into four bins as noted by diagonal lines and the top Gene Ontology term (molecular function) was noted along with the Benjamini corrected p value and top genes [93]. Note that, similar to findings from previous studies, the largest genes are commonly cell adhesion molecules, channel genes, and calcium ion binding genes that are important for neuronal function [23, 24]
