In order to assess the genetic defects in NFLE, we performed a mutation screening in 33 unrelated patients with sporadic NFLE by amplifying and sequencing bidirectionally TM 1-3 of CHRNA4, CHRNB2 and CHRNA2 which contain the mutations reported in ADNFLE.

To investigate this issue of phenotypic heterogeneity, we prospectively carried out a high-resolution 3-T magnetic resonance imaging (MRI) study in an ADNFLE family containing 10 affected members including one pharmacoresistant patient and carrying the V287L mutation of the CHRN beta2 subunit (CHRNB2).

Although over hundred families are on record, only a minority of them have been linked to mutations in the genes coding for the alpha4, alpha2 and beta2 (CHRNA4, CHRNA2, and CHRNB2) subunits of the nAChRs, indicating that ADNFLE is genetically heterogeneous despite a relatively homogeneous clinical picture.
