Abstract: | A paracentric inversion in the long arm of a number 7 chromosome was detected in an amniotic cell culture from a 41 year old woman, screened because of maternal age. The karyotype was 46, XX, inv(7) (q11q22). Her husband carried an identical inversion. The parents were advised that the pregnancy should continue and a healthy infant was born at term. Prenatal diagnosis and counselling for paracentric inversion heterozygotes are discussed in the light of published and unpublished cases. |
