In a majority of Wilms' tumors (WTs) there is an abnormal bipaternal pattern of expression at three imprinted loci, H19, IGF2 and KIP2, clustered on chromosome 11p15.5. We previously described biallelic expression of L23MRP, 40 kb downstream of H19. Here we map two additional genes, the first encoding a ubiquitously expressed RNA, 2G7, and the second encoding the fast isoform of skeletal muscle troponin-T (TNNT3), in the 55 kb of DNA downstream of L23MRP. 2G7 RNA is spliced and polyadenylated but lacks long open reading frames. 2G7 and TNNT3 are biallelically expressed in mid-fetal and adult human tissues and 2G7 shows persistent expression in WTs. The rat homologue of L23MRP is highly conserved and lies within 85 kb of H19 in a region of rat chromosome 1 which also contains IGF2 and TNNT3. Parallel expression of H19 and TNNT3 in different adult skeletal muscle types suggests that these genes may share an enhancer. These data outline multiple contiguous loci downstream of H19 which escape functional imprinting in humans. The rodent-human synteny of this region may facilitate a search for an imprinting domain boundary. © 1993 Oxford University Press Yuan Luwa Department of Pathology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA aut Qian Naifeng Department of Pathology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA aut Tycko Benjamin Department of Pathology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA aut Human Molecular Genetics Oxford University Press 5/12(1996-12), 1931-1937 0964-6906 5:12<1931 1996 5 hmg https://doi.org/10.1093/hmg/5.12.1931 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/hmg/5.12.1931 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Yuan Luwa Department of Pathology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA aut NATIONALLICENCE 700 1- Qian Naifeng Department of Pathology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA aut NATIONALLICENCE 700 1- Tycko Benjamin Department of Pathology, Columbia University College of Physicians and Surgeons, New York, NY 10032, USA aut NATIONALLICENCE 773 0- Human Molecular Genetics Oxford University Press 5/12(1996-12), 1931-1937 0964-6906 5:12<1931 1996 5 hmg Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
