Abstract: 

BACKGROUND: The aim of the present study was to investigate the chromosomal abnormalities and to identify the most prevalent or frequent type of chromosomal abnormalities in cases of amenorrhea from the southern region of India.
METHODS: A total of 637 cases with amenorrhea were analyzed using G- banding, C-banding, Silver staining, and fluorescence in situ hybridization was done wherever necessary.
RESULTS: Out of the 637 cases involved in our study, 132 abnormalities were detected. The incidence of chromosomal abnormalities in cases with primary and secondary amenorrhea was around 20.7 %. In addition to the numerical anomalies, various structural aberrations of the X chromosome like deletions, isochromosomes, duplications, ring chromosome, and also male karyotype were detected.
CONCLUSION: Review of the literature and overall incidence of chromosomal abnormalities in patients with amenorrhea suggests the need for cytogenetic analysis to be performed in all the cases referred for amenorrhea with or without short stature. Precise identification of chromosomal abnormalities helps in confirming the provisional diagnosis; it helps the secondary amenorrhea patients in assisted reproduction and to understand the clinical heterogeneity involved and in efficient genetic counseling.
