The incidence is said to be about 1% to 1.65 % in the general population. Despite 1 being categorised as a minor chromosomal rearrangement which does not correlate with abnormal phenotypes seen in healthy individuals, some reports in the literature raised conflicting views regarding the association with subfertility and abortions, abnormal clinical conditions and chromosomal abnormalities associated with this inversion. We studied retrospectively the incidence of pericentric inversion of chromosome 9 cases which was referred to our laboratory since 1969 and also analysed peripheral blood karyotypes in specimens collected from 1999 to 2002 and found the incidence to be % 1.65.trinfo:eu-repo/semantics/closedAccessReview Article15101121152-s2.0-0347420002N/A
