Specific Chromosomal Aberrations in Primary Amenorrhoea: Study on 3776 Cases from Indian Population
- 2 Downloads
To verify the prevalence of chromosomal abnormalities in women with primary amenorrhoea in India aiming at appropriate genetic counselling.
In a 16-year retrospective (2001–2016) study, 3776 women with primary amenorrhoea were evaluated. Chromosomal analysis of all the cases was done by GTG banding. Clinical history and other laboratory findings were taken into consideration to determine the diagnosis.
The karyotype results revealed 31.2% cases with chromosomal abnormalities (n = 1177/3776). In patients with abnormal chromosome complement, 31.2% exhibited numerical aberrations (n = 367) and 34.9% with structural aberrations (n = 411). About 33.9% of cases were with XY male karyotype (n = 399).
As per the literature till date, this study is the largest with high incidence of chromosomal abnormalities; early detection of abnormalities is necessary for guidance to reproductive management and genetic counselling.
