Ring Chromosome 19

This study shows the feasibility of using CGH for the identification of supernumerary marker chromosomes, even in fewer than 50% of cells, where no clinical or cytogenetic clues are present. [ncbi.nlm.nih.gov]

The detail raw data are presented in [Table 1a] (presence: ; absence: -). Del(5q/20q), dir(9p/12p), -(18/19/Y), and, at least, one marker was consistently present in 88% of the cells evaluated. [cancerjournal.net]

Two important clinical characteristics which were commonly present in our case and other patients are developmental delay and microcephaly. [eymj.org]

Dyserythropoiesis was present, with megaloblastoid change and binuclear erythrocytes. Lymphoid aggregates and extrinsic cells were not present. Marrow fibrosis was not seen. Megakaryocytes were present, but reduced in number. [hoajonline.com]

    Dual-color FISH images were digitally generated using the Isis FISH imaging software (MetaSystems). 300 cells were scored for each sample. FISH analysis showed a r(21) in 77% of examined cells and a monosomy 21 in 23% (300 cells investigated). [omicsonline.org]

  • Suggestibility

    Our findings strongly suggest that our patient's phenotype is largely attributable to partial 7pter trisomy and partial 7qter monosomy rather than mosaic supernumerary ring chromosome 19. [ncbi.nlm.nih.gov]

    The finding suggests that TOMM40 affects memory — even when ApoE4 is not a factor. [keck.usc.edu]

    Although these genes have been suggested to be associated with muscular dystrophy, hypercalcemia, and mental retardation, respectively, no such distinct phenotype was observed in our patient, possibly because it was duplication rather than deletion. [eymj.org]
