• Mosaic Chromosomal Aneuploidies Detection in Clinical Samples

  Mosaic chromosomal aneuploidy occurs when only a subset of cells carries an abnormal number of chromosomes. Mosaic aneuploidy has been reported in multiple types of diseases. Here we have developed a new sequencing-based approach to identify, characterize and quantify mosaic aneuploidy events in human tissue samples. This ongoing study has begun with results from sequencing data from two clinical patients, one with autism spectrum disorder (ASD) and the other with hemihyperplasia (OMIM 235000). We captured ~100,000 common SNPs from the samples to identify the nature of the mosaic aneuploidy events in each of the samples.

• Detection of Somatic Mutations In Vitro Aging Cells

  Deep sequencing was performed to analyze the prevalence of somatic mutations during in vitro cell aging. Primary dermal fibroblasts from healthy subjects of young and advanced age, from Hutchinson-Gilford progeria syndrome, and from Xeroderma Pigmentosum complementation group A (XPA) and C (XPC), were first restricted in number and then expanded in vitro. DNA was obtained from cells pre- and post-expansion and sequenced at high depth, over a cumulative 290 kb target region, including the exons of 44 aging-related genes. Allele frequencies of 58 somatic mutations differed between the pre- and post-cell culture expansion passages.

• Novel APC Promoter and Exon 1B Deletion and Allelic Silencing in Three Mutation-Negative Classic Familial Adenomatous Polyposis Families

  The ~80% of individuals with classic familial adenomatous polyposis (FAP) have detectable mutations in the coding sequence of the adenomatous polyposis coli (APC) gene. To investigate the 20% of families without detectable causative mutations, we used exome sequencing and second-generation sequencing of the APC locus including non-coding regions. We identified a novel ~11kb deletion 44kb upstream of APC that was present only in affected individuals of three kindreds. SNP analysis showed that this ~11kb deletion was accompanied by silencing of one of the APC alleles in blood-derived RNA of affected individuals.

• Mutation signatures in melanocytic nevi reveal characteristics of defective DNA repair

  Nevi are common benign melanocytic neoplasms that can be found on any skin location and share many of the genomic hallmarks of melanoma. In our recent report involving whole-exome sequencing of acquired nevi (Stark et al., 2018), ultra-violet radiation (UVR) related somatic mutation signatures (“signature 7”) (Alexandrov et al., 2013) were frequently observed in all lesions that were located on sun-exposed sites. In the study presented herein, we sought to investigate whether an independent Spanish cohort (Valencia, Spain) of minimally sun exposed nevi had genomic features consistent with our previous findings.

• Fetal hemoglobin in sickle cell disease patients from Tanzania

  Levels of fetal hemoglobin have been associated with differences in severity and outcome of sickle cell disease (SCD). While some genetic associations have been reported between SNPs and HbF level, little of the variance in the trait is explained, and most studies have focused on African American, rather than African samples. We have carried out a GWAS in a collection of SCD patients from Dar es Salaam, Tanzania. This sample represents a diverse, metropolitan collection of individuals from East Africa. Omni 2.5M genotypes and HbF levels (measured after 5 years of age) are available.

• Somatic mutations and clonal dynamics in healthy and cirrhotic human liver

  Chronic liver injury predisposes to cirrhosis and hepatocellular carcinoma, but how somatic mutations accumulate in liver disease is unexplored. We sequenced whole genomes of 400 microdissections of 100-500 hepatocytes from 5 normal and 6 cirrhotic livers. Compared to normal liver, cirrhotic liver had higher mutation burden, especially structural variants, including chromothripsis. Cirrhotic nodules were oligoclonal; sometimes entirely derived from a single, recent common ancestor. Clonal expansions millimeters in diameter occurred in cirrhosis in the absence of known driver mutations. Endogenous mutational processes predominated, although signatures of polycyclic aromatic hydrocarbon and aristolochic acid exposure occurred in some samples. Up to 10-fold within-patient variation in activity of exogenous signatures existed between adjacent cirrhotic nodules, with both clone-specific and microenvironmental forces shaping this heterogeneity. Synchronous hepatocellular carcinomas drew from the same repertoire of mutational signatures as background cirrhotic liver, but with higher burden. Somatic mutations chronicle the exposures, toxicity, regeneration and clonal structure of liver tissue as it progresses from health to disease.

• SARS-CoV-2 host genetics and COVID-19 outcomes in admixed Brazilians with extreme phenotypes

  COVID-19 comprises clinical outcomes of SARS-CoV-2 infection and is highly heterogeneous, ranging from asymptomatic individuals to deceased young adults without comorbidities. There is growing evidence that host genetics play an important role in COVID-19 severity, including inborn errors of immunity, age-related inflammation and immunosenescence. This study proposes a strategy of subject’s ascertainment based on phenotypic extremes to take part in genomic studies and elucidate intrinsic risk factors involved in COVID-19 severe outcomes. Different cohorts were collected and submitted to Next-Generation Sequencing (Whole exome and whole genome sequencing).

• Subclonal somatic copy number alterations emerge and dominate in recurrent osteosarcoma

  Multiple large-scale genomic profiling efforts have been undertaken in osteosarcoma to define the genomic drivers of tumorigenesis, therapeutic response, and disease recurrence. The spatial and temporal intratumor heterogeneity could also play a role in promoting tumor growth and treatment resistance. Here, we conducted longitudinal whole-genome sequencing of 37 tumor samples from eight patients with osteosarcoma that relapsed or became refractory to initial therapy. We found that the chemoresistant population in recurrent osteosarcoma is subclonal at diagnosis, emerges at the time of primary resection due to selective pressure from neoadjuvant chemotherapy, and is characterized by unique oncogenic amplifications.

• Mutational evolution in a lobular breast tumour profiled at single nucleotide resolution

  We have used next generation sequencing to sequence genomes (>43-fold coverage) and transcriptomes of an oestrogen-receptor-alpha-positive metastatic lobular breast cancer at depth. We found 32 somatic non-synonymous coding mutations present in the metastasis, and measured the frequency of these somatic mutations in DNA from the primary tumour of the same patient.

• Single-cell profiling reveals monocyte mitochondrial dysfunction in patients with cirrhosis progressing to acute-on-chronic liver failure

  We performed single-cell RNA-seq and CITE-seq in PBMC samples derived from patients with acutely decompensated cirrhosis at risk of developing ACLF, as well as from Healthy Donors. We identified a population of monocytes associated with disease progression. We also explored the presence of this cell population in blood samples by bulk RNA-sequencing.

• Subclonal variation in patients with pediatric T-lymphoblastic leukemia (T-ALL)

  Variations in TP53 and KRAS genes indicate a particularly poor prognosis in relapsed pediatric T-ALL. We hypothesized that these variations might be subclonally present at disease onset and contribute to relapse risk. To test this, we examined 386 children diagnosed with T-ALL, including more than 100 patients who relapsed as well as matched non-relapsing controls.

• Mitochondrial DNA mosaicism in human somatic cells

  Genomic alterations accumulate in the somatic cells throughout an individual’s lifetime. Recent sequencing studies have documented widespread mutations in the nuclear genome and the frequent clonal competition of normal cells carrying mutations. However, the landscape of mitochondrial DNA (mtDNA) heteroplasmy in normal human tissues is poorly understood. This study investigated the whole genome sequences (WGSs) of 2,096 clones established from non-neoplastic healthy single cells obtained from 31 donors. In addition, we analyzed 31 WGSs of neoplastic cells, including 12 clones established from adenomatous polyps from one individual with MUTYH-associated polyposis and 19 matched colorectal carcinomas from individuals who donated normal colorectal clones.
