Trisomy 20p is a chromosomal anomaly resulting from whole or partial duplication of the short arm of chromosome 20. It is a rarely reported syndrome and it is estimated that there are only a few cases of this condition worldwide, which hampers the phenotypic characterization of this entity. Conversely, müllerian anomalies include a group of congenital malformations of the uterus, vagina, cervix, and fallopian tubes resulting from alterations in the embryological development of the müllerian ducts. We report a case of pure trisomy 20p diagnosed using array comparative genomic hybridization (CGH) accompanied by a müllerian anomaly in a female patient with abnormal growth pattern, round face, coarse hair, broad nose, long palpebral fissure, epicanthus, and megaureter.
20号染色体短臂三体是一种由20号染色体短臂全部或部分重复导致的染色体异常。这是一种鲜有报道的综合征,据估计全球仅有少数该病症的病例,这妨碍了对该病症的表型特征描述。相反,苗勒管异常包括一组因苗勒管胚胎发育改变导致的子宫、阴道、宫颈和输卵管先天性畸形。我们报告了一例通过阵列比较基因组杂交(CGH)诊断出的单纯20号染色体短臂三体病例,该病例伴有苗勒管异常,患者为一名女性,具有生长模式异常、圆脸、毛发粗糙、宽鼻、睑裂长、内眦赘皮和巨输尿管等症状。
