Any deviation of the normal prenatal development right from gametogenesis may give rise to condition now known as disorders of sex development. XY gonadal dysgenesis is characterized by 46,XY chromosome complement with female phenotype and streak gonads. This study reports incidental finding of eight such cases.
To find out correlation between clinical findings and chromosome complement in cases presenting with menstrual dysfunction.
Prospective, cross-sectional study conducted in a tertiary healthcare center.
Chromosomes were studied after planting and harvesting through conventional short-term culture method. Attempt was made to correlate the cytogenetic findings with other clinical findings of cases.
Nil.
Hundred cases of menstrual dysfunction referred from other clinical departments were studied. Abnormal chromosomes were obtained in total ten cases where 46XY disorder of sex development was observed in eight cases and two- cases had Turner syndrome. It was observed that these cases belonged to primary and secondary amenorrhea only. There were six cases where the chromosomal complement was 46,XY and two cases with mosaicism of 46,XY/45,X. Patients with hypomenorrhea and oligomenorrhea had normal chromosomal findings.
It is possible to have normal looking females with normal development of secondary sex characters to have abnormal chromosome complement. Cytogenetic testing becomes inevitable in such cases. If possible, molecular diagnostic methods also can be employed for detailed description of derangement.
从配子发生开始的任何正常产前发育偏差都可能导致现在被称为性发育障碍的病症。XY性腺发育不全的特征是具有女性表型和条索状性腺的46,XY染色体组成。本研究报告了8例此类偶然发现的病例。
找出月经功能障碍病例的临床发现与染色体组成之间的相关性。
在一家三级医疗保健中心进行的前瞻性横断面研究。
通过传统的短期培养方法种植和收获后研究染色体。试图将细胞遗传学发现与病例的其他临床发现相关联。
无。
研究了从其他临床科室转诊的100例月经功能障碍病例。总共10例获得了异常染色体,其中8例观察到46XY性发育障碍,2例患有特纳综合征。观察到这些病例仅属于原发性和继发性闭经。有6例染色体组成为46,XY,2例为46,XY/45,X嵌合体。月经过少和月经稀发的患者染色体检查结果正常。
有可能出现具有正常第二性征发育的外观正常女性却有异常染色体组成的情况。在这种情况下,细胞遗传学检测变得不可避免。如果可能,分子诊断方法也可用于详细描述紊乱情况。
