Whole-exome sequencing revealed a de novo, heterozygous deleterious mutation c.400C>T (p.R13X) in WDR45, previously reported to be disease-causing and associated with early childhood global developmental delay and seizures other than epileptic spasms.
A girl with cardio-facio-cutaneous (CFC) syndrome due to a BRAF gene mutation (c.1454T→C, p.L485S) experienced repetitive epileptic spasms at the corrected age of 4 months.
