No TTGTA FAME3 expansions were identified in 169 WGS samples from an inhouse epilepsy cohort and 3202 samples from the 1000 Genomes Project with publicly available WGS data.21 We screened 1616 individuals with epilepsy and available WES data for evidence of large TTGTA expansions somewhere in their genome. The gene discussed is MARCHF6; the disease is epilepsy.
