Item Juvenile Paget’s Disease From Heterozygous Mutation of SP7 Encoding Osterix (Specificity Protein 7, Transcription Factor Sp7)(Elsevier, 2020-08) Whyte, Michael P.; Campeau, Philippe M.; McAlister, William H.; Roodman, G. David; Kurihara, Nori; Nenninger, Angela; Duan, Shenghui; Gottesman, Gary S.; Bijanki, Vinieth N.; Sedighi, Homer; Veis, Deborah J.; Mumm, Steven; Medicine, School of MedicineJuvenile Paget's disease (JPD) became in 1974 the commonly used name for ultra-rare heritable occurrences of rapid bone remodeling throughout of the skeleton that present in infancy or early childhood as fractures and deformity hallmarked biochemically by marked elevation of serum alkaline phosphatase (ALP) activity (hyperphosphatasemia). Untreated, JPD can kill during childhood or young adult life. In 2002, we reported that homozygous deletion of the gene called tumor necrosis factor receptor superfamily, member 11B (TNFRSF11B) encoding osteoprotegerin (OPG) explained JPD in Navajos. Soon after, other bi-allelic loss-of-function TNFRSF11B defects were identified in JPD worldwide. OPG inhibits osteoclastogenesis and osteoclast activity by decoying receptor activator of nuclear factor κ-B (RANK) ligand (RANKL) away from its receptor RANK. Then, in 2014, we reported JPD in a Bolivian girl caused by a heterozygous activating duplication within TNFRSF11A encoding RANK. Herein, we identify mutation of a third gene underlying JPD. An infant girl began atraumatic fracturing of her lower extremity long-bones. Skull deformity and mild hearing loss followed. Our single investigation of the patient, when she was 15 years-of-age, showed generalized osteosclerosis and hyperostosis. DXA revealed a Z-score of +5.1 at her lumbar spine and T-score of +3.3 at her non-dominant wrist. Biochemical studies were consistent with positive mineral balance and several markers of bone turnover were elevated and included striking hyperphosphatasemia. Iliac crest histopathology was consistent with rapid skeletal remodeling. Measles virus transcripts, common in classic Paget's disease of bone, were not detected in circulating mononuclear cells. Then, reportedly, she responded to several months of alendronate therapy with less skeletal pain and correction of hyperphosphatasemia but had been lost to our follow-up. After we detected no defect in TNFRSF11A or B, trio exome sequencing revealed a de novo heterozygous missense mutation (c.926C>G; p.S309W) within SP7 encoding the osteoblast transcription factor osterix (specificity protein 7, transcription factor SP7). Thus, mutation of SP7 represents a third genetic cause of JPD.Item Molecular classification and biomarkers of clinical outcome in breast ductal carcinoma in situ: Analysis of TBCRC 038 and RAHBT cohorts(Elsevier, 2022-12-12) Strand, Siri H.; Rivero-Gutiérrez, Belén; Houlahan, Kathleen E.; Seoane, Jose A.; King, Lorraine M.; Risom, Tyler; Simpson, Lunden A.; Vennam, Sujay; Khan, Aziz; Cisneros, Luis; Hardman, Timothy; Harmon, Bryan; Couch, Fergus; Gallagher, Kristalyn; Kilgore, Mark; Wei, Shi; DeMichele, Angela; King, Tari; McAuliffe, Priscilla F.; Nangia, Julie; Lee, Joanna; Tseng, Jennifer; Storniolo, Anna Maria; Thompson, Alastair M.; Gupta, Gaorav P.; Burns, Robyn; Veis, Deborah J.; DeSchryver, Katherine; Zhu, Chunfang; Matusiak, Magdalena; Wang, Jason; Zhu, Shirley X.; Tappenden, Jen; Ding, Daisy Yi; Zhang, Dadong; Luo, Jingqin; Jiang, Shu; Varma, Sushama; Anderson, Lauren; Straub, Cody; Srivastava, Sucheta; Curtis, Christina; Tibshirani , Rob; Angelo, Robert Michael; Hall , Allison; Owzar , Kouros; Polyak , Kornelia; Maley, Carlo; Marks, Jeffrey R.; Colditz, Graham A.; Hwang, E. Shelley; West , Robert B.; Medicine, School of MedicineDuctal carcinoma in situ (DCIS) is the most common precursor of invasive breast cancer (IBC), with variable propensity for progression. We perform multiscale, integrated molecular profiling of DCIS with clinical outcomes by analyzing 774 DCIS samples from 542 patients with 7.3 years median follow-up from the Translational Breast Cancer Research Consortium 038 study and the Resource of Archival Breast Tissue cohorts. We identify 812 genes associated with ipsilateral recurrence within 5 years from treatment and develop a classifier that predicts DCIS or IBC recurrence in both cohorts. Pathways associated with recurrence include proliferation, immune response, and metabolism. Distinct stromal expression patterns and immune cell compositions are identified. Our multiscale approach employed in situ methods to generate a spatially resolved atlas of breast precancers, where complementary modalities can be directly compared and correlated with conventional pathology findings, disease states, and clinical outcome.
