Characterisation of 16 polymorphic markers in the NF2 gene: application to hemizygosity detection
Neurofibromatosis type 2 (NF2) is an autosomal dominant disorder that predisposes to nervous system tumors. Point mutations are evidenced in about 50% of the NF2 patients and large genomic deletions account for approximately 33% of the NF2 gene alterations. To facilitate the deletion screening, 16 polymorphic markers were identified in the NF2 genomic sequence enabling an hemizygosity test in familial studies.
