Familial pachygyria in both genders related to a DCX mutation.

Abstract:

:Doublecortin (DCX) and tubulin play critical roles in neuronal migration. DCX mutations usually cause anterior dominant lissencephaly in males and subcortical band heterotopia (SBH) in females. We used whole-exome sequencing to investigate causative gene variants in a large family with late-childhood-onset focal epilepsy and anterior dominant pachygyria without SBH in both genders. Two potential variants were found for the genes encoding DCX and beta tubulin isotype 1 (TUBB1). The novel DCX mutation (p.D90G, NP_000546.2) appeared to be a major causative variant, whereas the novel mutation of TUBB1 (p.R62fsX, NP_110400.1) was found only in patients with more-severe intellectual disability after gender matching. We report an unusual DCX-related disorder exhibiting familial pachygyria without SBH in both genders.
