A case of trisomy 20?
Chromosome determination in a girl who at birth had an abnormal appearance and a cat's cry, and later a poor weight gain and psychomotor retardation, showed a probable trisomy of chromosome pair no. 20. The analysis was made by means of photometric examination of G-banded chromosomes from lymphocyte cultures. The deviating chromosome was identified in fibroblast cultures as well.
