| GENE MAPPING & DOSAGE STUDIES - CHROMOSOME 21 |
Gene dosage studies and subsequent karyotype analysis published by Dahl et al (Am J Hum Genet 43:502-510,1988) reported the karyotype of this cell culture to be 45,XY,-4,-21,+der(4),t(4;21)(p15;q21). |

| Cytogenetics |
Chromosome 21: ANEUPLOID Aneuploid Segment (-)21pter>21q21 |
|
Chromosome 21: DERIVATIVE CHROMOSOME Aneuploid Segment (-)21pter>21q21 |
|
Chromosome 4: DERIVATIVE CHROMOSOME Aneuploid Segment (-)4pter>4p16 |
| Remarks |
60% of normal superoxide dismutase-1 activity; multiple malformations & severe psychomotor retardation; 70% of normal SOD-1 RNA in fibroblasts; gene dosage studies suggest a translocation rather than a monosomy for chromosome #21 |
