Tumor mutational burden (TMB) represents a new determinant of clinical benefit from immune checkpoint blockade that identifies responders independent PD‐L1 expression levels and is currently being explored in trials. Although TMB can be measured directly by comprehensive genomic approaches such as whole‐genome exome sequencing, broad availability, short turnaround times, costs amenability to formalin‐fixed paraffin‐embedded tissue support the use gene panel sequencing for approximating...

Next‐generation sequencing has become a cornerstone of therapy guidance in cancer precision medicine and an indispensable research tool translational oncology. Its rapidly increasing use during the last decade expanded options for targeted tumor therapies, molecular boards have grown accordingly. However, with detection genetic alterations, their interpretation more complex error‐prone, potentially introducing biases reducing benefits clinical practice. To facilitate interdisciplinary...

Assessment of Tumor Mutational Burden (TMB) for response stratification cancer patients treated with immune checkpoint inhibitors is emerging as a new biomarker. Commonly defined the total number exonic somatic mutations, TMB approximates amount neoantigens that potentially are recognized by system. While whole exome sequencing (WES) an unbiased approach to quantify TMB, implementation in diagnostics hampered tissue availability well time and cost constrains. Conversely, panel-based targeted...

Homologous repair deficiency (HRD) is present in many cancer types at variable prevalence and can indicate response to platinum-based chemotherapy PARP inhibition. We developed a tumor classification system based on the loss of function genes homologous recombination (HRR) pathway. To this end, somatic germline alterations BRCA1/2 140 other HRR were included assessed for impact gene function. Additionally, information allelic hit type BRCA1 promoter hypermethylation was included. The HRDsum...

Abstract Background Cholangiocarcinoma (CCA) is a primary malignancy of the biliary tract with dismal prognosis. Recently, several actionable genetic aberrations were identified significant enrichment in intrahepatic CCA, including FGFR2 gene fusions prevalence 10–15%. Recent clinical data demonstrate that these are druggable second-line setting advanced/metastatic disease and efficacy earlier lines therapy being evaluated ongoing trials. This scenario warrants standardised molecular...

Although heritability of human body weight is assumed to be high, only a small fraction the variance can as yet attributed molecular genetic factors. Single monogenic forms obesity have been identified. Functionally relevant coding mutations in melanocortin-4 receptor gene occur 1–6% extremely obese children and adolescents thus represent most common major effect. Genome-wide association studies (GWAS) had previously identified 14 loci with genome-wide significant (p < 5 x 10–8)...

Abstract The heritability of attention deficit hyperactivity disorder (ADHD) is approximately 0.8. Despite several larger scale attempts, genome‐wide association studies (GWAS) have not led to the identification significant results. We performed a GWAS based on 495 German young patients with ADHD (according DSM‐IV criteria; Human660W‐Quadv1; Illumina, San Diego, CA) and 1,300 population‐based adult controls (HumanHap550v3; Illumina). Some genes neighboring single nucleotide polymorphisms...

Anaplastic lymphoma kinase (ALK) sequencing can identify resistance mechanisms and guide next-line therapy in ALK+ non-small-cell lung cancer (NSCLC), but the clinical significance of other rebiopsy findings remains unclear. We analysed all stage-IV NSCLC patients with longitudinally assessable TP53 status treated our institutions (n = 62). Patients mutations at baseline (TP53mutbas, n 23) had worse overall survival (OS) than initially wild-type tumours (TP53wtbas, 39, 44 vs. 62 months...
