|[c.5555T>C] Clinical description|
The mutation is a heterozygous point mutation, which was detected in both affected members of family, but not in their mother, who was unaffected. Notably, one of the affected members of this family is the one with SMEI. His sister, who carried the same mutation, had a milder phenotype of GEFS+, whereas the father, who had died at the time of the study, had FS+(Annesi G,et al. Epilepsia, 2003, 44(9):1257–1258. ).
