Preliminary cytogenetic studies in Hazara division

ABSTRACT

Cytogenetic studies were performed on 185 people in Hazara Division from January 1, 1993 to January 31, 1994; these included normal people, as well as selected groups of patients suspected of having various chromosomal abnormalities. Suspected patients were selected from special education centres, hospitals or the community and belonged to the following categories mental retardation, congenital anomalies, Down's syndrome, Turner's syndrome, primary and secondary amenorrhoea, infertility, undescended testes, azoospermia and leukaemias. Abnormal karyotypes were found only in cases of Down's and Turner's syndromes and in Leukaemias. Further studies in these and other related groups are expected to continue in the future
