We currently offer linkage analysis of the NF2 gene using PCR amplification and flanking and introgenic markers. Linkage analysis is recommended when 1) the mutation screening and MLPA analysis of the family proband is negative, and 2) there are multiple affected and unaffected family members spanning at least two generations.
Results of DNA analysis will be communicated in a written report to the referring professional.
DNA analysis is appropriate for the study of affected patients, for diagnostic confirmation in a presumed affected patient, and in pre-symptomatic and prenatal testing situations after the family mutation has been identified in the proband.
