PACS2 is also a gene described in 2018 by Olson et al. [31] as being causative of neonatal-onset developmental and/or epileptic encephalopathy, facial dysmorphism, and cerebellar dysgenesis, and similar to NBEA gene, it was not included at the time of the analysis in the clinical panel requested for the analysis of patients NGS data. Here, PACS2 is linked to Epileptic encephalopathy.
