Abstract: | Two sisters with statomotor developmental retardation microcephaly, hydrocephalus internus and externus without signs of pressure, heart defect (ventricular septal defect), early pulmonary resistance and characteristic facial changes were found to have the same unbalanced karyotype with partial trisomy 5q3300 leads to 5qter and partial monosomy 8p2300 leads to 8pter, derived from a balanced reciprocal paternal translocation: 46,XY,t(5;8)(q3300;p2300). The older girl was tested for the erythrocyte enzyme glutathion reductase. She had normal values. |
