Abstract Background The RecQ Like Helicase (RECQL) gene has previously been shown to predispose to breast cancer mainly in European populations, in particular to estrogen receptor (ER) and/or progesterone receptor (PR) positive tumor. Here, we investigated the contribution of pathogenic RECQL germline variants to hereditary breast cancer in early-onset and familial breast cancer patients from Pakistan. Methods Comprehensive RECQL variant analysis was performed in 302 BRCA1 and BRCA2 negative patients with ER and/or PR positive breast tumors using denaturing high-performance liquid chromatography followed by DNA sequencing. Novel variants were classified using Sherloc guidelines. Results One novel pathogenic protein-truncating variant (p.W75*) was identified in a 37-year-old familial breast cancer patient. The pathogenic variant frequencies were 0.3% (1/302) in early-onset and familial breast cancer patients and 0.8% (1/133) in familial patients. Further, three novel variants of unknown significance, p.I141F, p.S182S, and p.C475C, were identified in familial breast cancer patients at the age of 47, 68, and 47 respectively. All variants were absent in 250 controls. Conclusions Our data suggest that the RECQL gene plays a negligible role in breast cancer predisposition in Pakistan.

AbstractAimThe aim of this study is to review the legal implications, the technology, the indications and the management of women with a familial background of breast and/or ovarian cancer.MethodsWe have reviewed the literature and national Austrian guidelines to describe the uptake of genetic counseling and the management options offered in Austria.ResultsGenetic testing for theConclusionWhile readily available country-wide counseling has led to an increase in counseling and testing, Austrian legislation mandates “non-directional counseling” resulting in a comparatively low uptake of prophylactic surgery.
