Using TGex software (LifeMap Sciences, United States), 9 candidate variants in 9 genes (UBAP2L, CUX2, CACNA1I, SAMD12, HERC2, IQSEC1, NFASC, RERE, PLAA) were mapped to known phenotypes including seizures, intellectual disability, developmental delay, motor delay, language delay and autistic behaviour. The gene discussed is RERE; the disease is Intellectual disability.
