They affect males and females, with an estimated worldwide prevalence of 1 in 5000 live births. These malformations are clinically heterogeneous and can be part of a syndromic presentation (syndromic ARM) or as a nonsyndromic entity (nonsyndromic ARM). Despite the well-recognized heritability of nonsyndromic ARM, the genetic etiology in most patients is unknown. In this study, we describe three siblings with diverse congenital anomalies of the genitourinary system, anemia, delayed milestones, and skeletal anomalies. Genome sequencing identified a novel, paternally inherited heterozygous Caudal type Homeobox 2 (CDX2) variant (c.722A > G (p.Glu241Gly)), that was present in all three affected siblings. The variant identified in this family is absent from population databases and predicted to be damaging by most in silico pathogenicity tools. So far, only two other reports implicate variants in CDX2 with ARMs. Remarkably, the individuals described in these studies had similar clinical phenotypes and genetic alterations in CDX2 CDX2 encodes a transcription factor and is considered the master regulator of gastrointestinal development. This variant maps to the homeobox domain of the encoded protein, which is critical for interaction with DNA targets. Our finding provides a potential molecular diagnosis for this family's condition and supports the role of CDX2 in anorectal anomalies. It also highlights the clinical heterogeneity and variable penetrance of ARM predisposition variants, another well-documented phenomenon. Finally, it underscores the diagnostic utility of genomic profiling of ARMs to identify the genetic etiology of these defects.","PeriodicalId":10360,"journal":{"name":"Cold Spring Harbor Molecular Case Studies","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10815271/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41193559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on gene expression profiling, it has been subdivided into germinal center (GC)-derived and activated B-cell (ABC) types. Advances in molecular methodologies have further refined the subclassification of DLBCL, based on recurrent genetic abnormalities. Here, we describe a distinct case of DLBCL that presented in leukemic form. DNA sequencing targeting 275 genes revealed pathogenically relevant mutations of CD79B, MyD88, TP53, TBL1XR1, and PIM1 genes, indicating that this lymphoma would be best classified as MCD/C5 DLBCL, an ABC subtype. Despite an initial good clinical response to BTK inhibitor ibrutinib, anti-CD20 antibody rituxan, alkylating agent bendamustine, and hematopoietic stem-cell transplant, the lymphoma relapsed, accompanied by morphologic and molecular evidence of disease progression. Specifically, the recurrent tumor developed loss of TP53 heterozygosity (LOH) and additional chromosomal changes central to ABC DLBCL pathogenesis, such as PRDM1 loss. Acquired resistance to ibrutinib and rituxan was indicated by the emergence of BTK and FOXO1 mutations, respectively, as well as apparent activation of alternative cell-activation pathways, through copy-number alterations (CNAs), detected by high-resolution chromosomal microarrays. In vitro, studies of relapsed lymphoma cells confirmed resistance to standard BTK inhibitors but sensitivity to vecabrutinib, a noncovalent inhibitor active against both wild-type as well as mutated BTK. In summary, we provide in-depth molecular characterization of a de novo leukemic DLBCL and discuss mechanisms that may have contributed to the lymphoma establishment, progression, and development of drug resistance.","PeriodicalId":10360,"journal":{"name":"Cold Spring Harbor Molecular Case Studies","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10815299/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41093560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
