    Abstract Objective:To evaluate the impact of faecal immunochemical testing (FIT) prioritisation to mitigate the impact of delay in the 2-week-wait (2WW) colorectal cancer (CRC) urgent diagnostic pathway consequent from the Coronavirus disease 2019 (COVID-19) pandemic.Design:We modelled the reduction in CRC survival and life years lost resultant from per-patient delays of 2-6 months in the 2WW pathway. We stratified by age-group, individual-level benefit in CRC cancer survival versus age-specific nosocomial COVID-19-related fatality per referred patient undergoing colonoscopy. We modelled mitigation strategies using thresholds of FIT triage of 2, 10 and 150 ug Hb/g to prioritise 2WW referrals for colonoscopy. To construct the underlying models, we employed 10-year net CRC survival for England 2008-2017, 2WW pathway CRC case and referral volumes and per-day-delay hazard ratios generated from observational studies of diagnosis-to-treatment interval.Results:Delay of 2/ 4/ 6 months across all 11,266 CRC patients diagnosed per typical year via the 2WW pathway were estimated to result in 653/ 1,419/ 2,250 attributable deaths and loss of 9,214/ 20,315/ 32,799 life years. Risk-benefit from urgent investigatory referral is particularly sensitive to nosocomial COVID-19 infection rates for patients aged >60. Prioritisation out of delay for the 18% of symptomatic referrals with FIT >10 ug Hb/g would avoid 89% of these deaths attributable to delay, whilst reducing immediate requirement for colonoscopy by >80%.Conclusions:Delays in the pathway to CRC diagnosis and treatment have potential to cause significant mortality and loss of life years. FIT-triage of symptomatic patients in primary care could streamline access to colonoscopy, reduce delays for true-positive CRC cases and reduce nosocomial COVID-19 mortality in older true-negative 2WW referrals. However, this strategy offers benefit only in short-term rationalisation of limited endoscopy services: the appreciable false-negative rate in symptomatic patients of FIT means colonoscopy is still required in the majority.

    Abstract Context: To date, penetrance figures for medullary thyroid cancer (MTC) for variants in rearranged during transfection (RET) have been estimated from families ascertained because of the presence of MTC.
    Objective: To gain estimates of penetrance, unbiased by ascertainment, we analyzed 61 RET mutations assigned as disease causing by the American Thyroid Association (ATA) in population whole-exome sequencing data.
    Design: For the 61 RET mutations, we used analyses of the observed allele frequencies in ∼51,000 individuals from the Exome Aggregation Consortium (ExAC) database that were not contributed via The Cancer Genome Atlas (TCGA; non-TCGA ExAC), assuming lifetime penetrance for MTC of 90%, 50%, and unbounded.
    Setting: Population-based.
    Results: Ten of 61 ATA disease-causing RET mutations were present in the non-TCGA ExAC population with observed frequency consistent with penetrance for MTC of >90%. For p.Val804Met, the lifetime penetrance for MTC, estimated from the allele frequency observed, was 4% [95% confidence interval (CI), 0.9% to 8%].
    Conclusions: Based on penetrance analysis in carrier relatives of p.Val804Met-positive cases of MTC, p.Val804Met is currently understood to have high-lifetime penetrance for MTC (87% by age 70), albeit of later onset of MTC than other RET mutations. Given our unbiased estimate of penetrance for RET p.Val804Met of 4% (95% CI, 0.9% to 8%), the current recommendation by the ATA of prophylactic thyroidectomy as standard for all RET mutation carriers is likely inappropriate.

    Abstract Background: Studies evaluating the association between peripheral blood leukocyte telomere length (LTL) and testicular germ cell tumor (TGCT) risk have produced conflicting results.
    Methods: Using available genotype data from the Testicular Cancer Consortium (TECAC), polygenic risk score and Mendelian randomization analyses of genetic variants previously associated with LTL were used to assess potential etiologic associations between telomere length and TGCT risk.
    Results: Genetically inferred telomere length was not associated with TGCT risk among 2,049 cases and 6,921 controls with individual-level genotype data (OR, 1.02; 95% confidence interval, 0.97-1.07). Mendelian randomization analyses using summary statistic data further indicated no evidence for an association between telomere length and TGCT risk among all available TECAC participants (3,558 cases and 13,971 controls).
    Conclusions: Our analyses in the largest molecular genetic testicular cancer study to date provide no evidence for an association between genetically inferred peripheral blood LTL and TGCT risk.
    Impact: The lack of evidence for an overall association indicates that peripheral blood LTL is likely not a strong biomarker for TGCT risk.

    Abstract Purpose: Conditions and thresholds applied for evidence weighting of within-codon concordance (PM5) for pathogenicity vary widely between laboratories and expert groups. Because of the sparseness of available clinical classifications, there is little evidence for variation in practice.
    Methods: We used as a truthset 7541 dichotomous functional classifications of BRCA1 and MSH2, spanning 311 codons of BRCA1 and 918 codons of MSH2, generated from large-scale functional assays that have been shown to correlate excellently with clinical classifications. We assessed PM5 at 5 stringencies with incorporation of 8 in silico tools. For each analysis, we quantified a positive likelihood ratio (pLR, true positive rate/false positive rate), the predictive value of PM5-lookup in ClinVar compared with the functional truthset.
    Results: pLR was 16.3 (10.6-24.9) for variants for which there was exactly 1 additional colocated deleterious variant on ClinVar, and the variant under examination was equally or more damaging when analyzed using BLOSUM62. pLR was 71.5 (37.8-135.3) for variants for which there were 2 or more colocated deleterious ClinVar variants, and the variant under examination was equally or more damaging than at least 1 colocated variant when analyzed using BLOSUM62.
    Conclusion: These analyses support the graded use of PM5, with potential to use it at higher evidence weighting where more stringent criteria are met.

    Abstract Testicular germ cell tumour (TGCT), the most common cancer in young men, has a significant heritable basis that has long raised questions as to the existence of underlying major high-penetrance susceptibility gene(s). To determine the contribution of rare gene mutations to the inherited risk of TGCT, we analysed germline whole-exome data for 919 TGCT cases and 1609 cancer-free controls. We compared frequencies between TGCT cases and controls of rare (<1%) and low-frequency (1-5%) coding variants (1) individually and (2) collapsed at the gene level via burden testing (T1, disruptive; T2, all deleterious; and T3, all nonsynonymous) using Fisher's exact test with Bonferroni correction of significance thresholds. No individual variant or individual gene showed a significant association with TGCT after correction for multiple testing. In the largest whole-exome sequencing study of testicular cancer reported to date, our findings do not support the existence of a major high-penetrance TGCT susceptibility gene (of odds ratio >10 and allele frequency [combined]>0.01%). Owing to its power, this study cannot exclude the existence of susceptibility genes responsible for occasional TGCT families or of rare mutations that confer very modest relative risks. In concert with findings from genome-wide association studies, our data support the notion that inherited susceptibility is largely polygenic with substantial contribution from common variation.
    Patient summary: In the largest study of its kind, we sequenced ∼20 000 genes in 919 men with testicular germ cell tumour (TGCT) and 1609 TGCT-free individuals and found no evidence of a single major gene underlying predisposition to TGCT (in the manner of BRCA1 for breast cancer). Instead, familial risk of TGCT is likely to be due to varying dosages of hundreds of minor genetic factors.

    Abstract BRWD3 has been described as a cause of X-linked intellectual disability, but relatively little is known about the specific phenotype. We report the largest BRWD3 patient series to date, comprising 17 males with 12 distinct null variants and 2 partial gene deletions. All patients presented with intellectual disability, which was classified as moderate (65%) or mild (35%). Behavioral issues were present in 75% of patients, including aggressive behavior, attention deficit/hyperactivity and/or autistic spectrum disorders. Mean head circumference was +2.8 SD (2.8 standard deviations above the mean), and mean BMI was +2.0 SD (in the context of a mean height of +1.3 SD), indicating a predominant macrocephaly/obesity phenotype. Shared facial features included a tall chin, prognathism, broad forehead, and prominent supraorbital ridge. Additional features, reported in a minority (<30%) of patients included cryptorchidism, neonatal hypotonia, and small joint hypermobility. This study delineates the clinical features associated with BRWD3 null variants and partial gene deletions, and suggests that BRWD3 should be included in the differential diagnosis of patients with an overgrowth-intellectual disability (OGID) phenotype, particularly in male patients with a mild or moderate intellectual disability associated with macrocephaly and/or obesity.

    Abstract Overgrowth-intellectual disability (OGID) syndromes are characterized by increased growth (height and/or head circumference ≥+2 SD) in association with an intellectual disability. Constitutive EED variants have previously been reported in five individuals with an OGID syndrome, eponymously designated Cohen-Gibson syndrome and resembling Weaver syndrome. Here, we report three additional individuals with constitutive EED variants, identified through exome sequencing of an OGID patient series. We compare the EED phenotype with that of Weaver syndrome (56 individuals), caused by constitutive EZH2 variants. We conclude that while there is considerable overlap between the EED and EZH2 phenotypes with both characteristically associated with increased growth and an intellectual disability, individuals with EED variants more frequently have cardiac problems and cervical spine abnormalities, boys have cryptorchidism and the facial gestalts can usually be distinguished.

    Abstract While most testicular germ cell tumours (TGCTs) exhibit exquisite sensitivity to platinum chemotherapy, ~10% are platinum resistant. To gain insight into the underlying mechanisms, we undertake whole exome sequencing and copy number analysis in 40 tumours from 26 cases with platinum-resistant TGCT, and combine this with published genomic data on an additional 624 TGCTs. We integrate analyses for driver mutations, mutational burden, global, arm-level and focal copy number (CN) events, and SNV and CN signatures. Albeit preliminary and observational in nature, these analyses provide support for a possible mechanistic link between early driver mutations in RAS and KIT and the widespread copy number events by which TGCT is characterised.
