P. Englefield et al., LOSS OF HETEROZYGOSITY ON CHROMOSOME-22 IN OVARIAN-CARCINOMA IS DISTAL TO AND IS NOT ACCOMPANIED BY MUTATIONS IN NF2 AT 22Q12, British Journal of Cancer, 70(5), 1994, pp. 905-907
Frequent loss of heterozygosity (LOH) has been reported on 22q in ovar
ian carcinoma, implying the presence of a tumour-suppressor gene. The
neurofibromatosis type 2 gene (NF2) at 22q12 is a plausible candidate.
Analysis of 9 of the 17 exons of NF2 by single-strand conformational
polymorphism (SSCP) in 67 ovarian carcinomas did not detect any somati
c mutations, suggesting that NF2 is not involved in the pathogenesis o
f ovarian carcinoma. LOH data support this conclusion and that the put
ative tumour-suppressor gene lies distal to NF2, beyond D22S283.
