CACNB1 and autism: Another genome-wide analysis queried TR expansions in genomes from autism families and population controls (8448 samples from MSSNG project, 9096 samples from Simons Simplex Collection, 2504 samples from 1000 Genomes project), reporting an increased rate of TR expansions in autism-affected children (23.3%) compared to unaffected children (20.7%), along with the identification of TREs in known risk genes, such as DMPK and FXN and within many novel loci, such as CACNB1 [51].
