    Description: So far, two genes associated with familial melanoma have been identified, accounting for a minority of genetic risk in families. Mutations in CDKN2A account for approximately 40% of familial cases, and predisposing mutations in CDK4 have been reported in a very small number of melanoma kindreds. Here we report the whole-genome sequencing of probands from several melanoma families, which we performed in order to identify other genes associated with familial melanoma. We identify one individual carrying a novel germline variant (coding DNA sequence c.G1075A; protein sequence p.E318K; rs149617956) in the melanoma-lineage-specific oncogene microphthalmia-associated transcription factor (MITF). Although the variant co-segregated with melanoma in some but not all cases in the family, linkage analysis of 31 families subsequently identified to carry the variant generated a log of odds (lod) score of 2.7 under a dominant model, indicating E318K as a possible intermediate risk variant. Consistent with this, the E318K variant was significantly associated with melanoma in a large Australian case-control sample. Likewise, it was similarly associated in an independent case-control sample from the United Kingdom. In the Australian sample, the variant allele was significantly over-represented in cases with a family history of melanoma, multiple primary melanomas, or both. The variant allele was also associated with increased naevus count and non-blue eye colour. Functional analysis of E318K showed that MITF encoded by the variant allele had impaired sumoylation and differentially regulated several MITF targets. These data indicate that MITF is a melanoma-predisposition gene and highlight the utility of whole-genome sequencing to identify novel rare variants associated with disease susceptibility.〈br /〉〈br /〉〈a href="" target="_blank"〉〈img src="" border="0"〉〈/a〉   〈a href="" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yokoyama, Satoru -- Woods, Susan L -- Boyle, Glen M -- Aoude, Lauren G -- MacGregor, Stuart -- Zismann, Victoria -- Gartside, Michael -- Cust, Anne E -- Haq, Rizwan -- Harland, Mark -- Taylor, John C -- Duffy, David L -- Holohan, Kelly -- Dutton-Regester, Ken -- Palmer, Jane M -- Bonazzi, Vanessa -- Stark, Mitchell S -- Symmons, Judith -- Law, Matthew H -- Schmidt, Christopher -- Lanagan, Cathy -- O'Connor, Linda -- Holland, Elizabeth A -- Schmid, Helen -- Maskiell, Judith A -- Jetann, Jodie -- Ferguson, Megan -- Jenkins, Mark A -- Kefford, Richard F -- Giles, Graham G -- Armstrong, Bruce K -- Aitken, Joanne F -- Hopper, John L -- Whiteman, David C -- Pharoah, Paul D -- Easton, Douglas F -- Dunning, Alison M -- Newton-Bishop, Julia A -- Montgomery, Grant W -- Martin, Nicholas G -- Mann, Graham J -- Bishop, D Timothy -- Tsao, Hensin -- Trent, Jeffrey M -- Fisher, David E -- Hayward, Nicholas K -- Brown, Kevin M -- 10118/Cancer Research UK/United Kingdom -- 10589/Cancer Research UK/United Kingdom -- AR043369-14/AR/NIAMS NIH HHS/ -- C490/A11021/Cancer Research UK/United Kingdom -- C588/A10589/Cancer Research UK/United Kingdom -- C588/A4994/Cancer Research UK/United Kingdom -- C8197/A10123/Cancer Research UK/United Kingdom -- C8216/A6129/Cancer Research UK/United Kingdom -- CA88363/CA/NCI NIH HHS/ -- K24CA149202/CA/NCI NIH HHS/ -- P50CA9368/CA/NCI NIH HHS/ -- R01 AR043369/AR/NIAMS NIH HHS/ -- R01 CA-83115-01A2/CA/NCI NIH HHS/ -- R01 CA088363/CA/NCI NIH HHS/ -- R01 CA088363-09/CA/NCI NIH HHS/ -- R01 CA83115/CA/NCI NIH HHS/ -- England -- Nature. 2011 Nov 13;480(7375):99-103. doi: 10.1038/nature10630.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, Cutaneous Biology Research Center, Massachusetts General Hospital, Harvard Medical School, Massachusetts 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="" target="_blank"〉PubMed〈/a〉

    Description: Objectives To assess the feasibility of delivering and evaluating a weight management (WM) programme for overweight patients with a family history (FH) of breast cancer (BC) or colorectal cancer (CRC). Study design A two-arm (intervention vs usual care) randomised controlled trial. Setting National Health Service (NHS) Tayside and NHS Grampian. Participants People with a FH of BC or CRC aged≥18 years and body mass index of ≥25 kg/m 2 referred to NHS genetic services. Intervention Participants were randomised to a control (lifestyle booklet) or 12-week intervention arm where they were given one face-to-face counselling session, four telephone consultations and web-based support. A goal of 5% reduction in body weight was set, and a personalised diet and physical activity (PA) programme was provided. Behavioural change techniques (motivational interviewing, action and coping plans and implementation intentions) were used. Primary outcome Feasibility measures: recruitment, programme implementation, fidelity measures, achieved measurements and retention, participant satisfaction assessed by questionnaire and qualitative interviews. Secondary outcomes Measured changes in weight and PA and reported diet and psychosocial measures between baseline and 12-week follow-up. Results Of 480 patients approached, 196 (41%) expressed interest in the study, and of those, 78 (40%) patients were randomised. Implementation of the programme was challenging within the time allotted and fidelity to the intervention modest (62%). Qualitative findings indicated the programme was well received. Questionnaires and anthropometric data were completed by 〉98%. Accelerometer data were attained by 84% and 54% at baseline and follow-up, respectively. Retention at 12 weeks was 76%. Overall, 36% of the intervention group (vs 0% in control) achieved 5% weight loss. Favourable increases in PA and reduction in dietary fat were also reported. Conclusions A lifestyle programme for people with a family history of cancer is feasible to conduct and acceptable to participants, and indicative results suggest favourable outcomes. Trial registration number ISRCTN13123470; Pre-results.
