Abstract

Although the spliceogenic nature of the BRCA2 c.68-7T > A variant has been demonstrated, its association with cancer risk remains controversial. In this study, we accurately quantified by real-time PCR and digital PCR the BRCA2 isoforms retaining or missing exon 3. In addition, the combined odds ratio for causality of the variant was estimated using genetic and clinical data, and its associated cancer risk was estimated by case-control analysis in 83,636 individuals. Co-occurrence in trans with pathogenic BRCA2 variants was assessed in 5,382 families. Exon 3 exclusion rate was 4.5-fold higher in variant carriers (13%) than controls (3%), indicating an exclusion rate for the c.68-7T > A allele of approximately 20%. The posterior probability of pathogenicity was 7.44 × 10-115. There was neither evidence for increased risk of breast cancer (OR 1.03; 95% CI 0.86-1.24), nor for a deleterious effect of the variant when co-occurring with pathogenic variants. Our data provide for the first time robust evidence of the non-pathogenicity of the BRCA2 c.68-7T > A. Genetic and quantitative transcript analyses together inform the threshold for the ratio between functional and altered BRCA2 isoforms compatible with normal cell function. These findings might be exploited to assess the relevance for cancer risk of other BRCA2 spliceogenic variants. This article is protected by copyright. All rights reserved.

Abstract

A girl with aniridia, microphthalmia, microcephaly and café au lait macules was found to have mutations in PAX6, NF1 and OTX2. A novel PAX6 missense mutation (p.R38W) was inherited from her mother whose iris phenotype had not been evident because of ocular neurofibromatosis. Analysis of the NF1 gene in the proband, prompted by the mother's diagnosis and the presence of café au lait spots, revealed a nonsense mutation (p.R192X). Subsequently an OTX2 nonsense mutation (p.Y179X) was identified and shown to be inherited from her father who was initially diagnosed with Leber's congenital amaurosis. Since individual mutations in PAX6, OTX2 or NF1 can cause a variety of severe developmental defects, the proband's phenotype is surprisingly mild. This case shows that patients with complex phenotypes should not be eliminated from subsequent mutation analysis after one or even two mutations are found.European Journal of Human Genetics (2007) 15, 898–901; doi:10.1038/sj.ejhg.5201826; published online 4 April 2007 [ABSTRACT FROM AUTHOR]
