Robertsonian translocations are the most common form of chromosomal abnormalities that specifically involve the acrocentric chromosomes. Robertsonian translocation between chromosomes 13,14 and 14,21 are the most frequently reported. Infertility is common in genetically balanced carriers of these translocations, and their conceptions are more likely to have imbalances. Here we have reported a case of an 18-year-old female presenting with a complaint of primary amenorrhea. Cytogenetic analysis revealed a familial case of maternally inherited Robertsonian translocation (rob(13;14)(q10;q10)) affecting all the siblings. Genetic counseling and genetic testing are recommended especially in familial cases as the carriers are normal but can lead to several genetic disorders in their future generation.
罗伯逊易位是最常见的染色体异常形式,特别涉及近端着丝粒染色体。13号与14号染色体以及14号与21号染色体之间的罗伯逊易位是最常报道的。在这些易位的遗传平衡携带者中,不孕很常见,而且他们怀孕时更有可能出现染色体不平衡。在此,我们报告了一例18岁女性主诉原发性闭经的病例。细胞遗传学分析显示这是一个家族性病例,母亲遗传的罗伯逊易位(rob(13;14)(q10;q10))影响了所有兄弟姐妹。尤其在家族性病例中,建议进行遗传咨询和基因检测,因为携带者外表正常,但可能在其后代中导致多种遗传疾病。
