Partial trisomy 3p results from either unbalanced translocation or de novo duplication. Common clinical features consist of dysmorphic facial features, congenital heart defects, psychomotor and mental retardation, abnormal muscle tone, and hypoplastic genitalia. In this paper, we report a case of partial trisomy 3p with rare clinical manifestations. A full-term, female newborn was transferred to our clinic. She had cleft lip-plate, dysgenesis of the corpus callosum, patent ductus arteriosus, pulmonary hypertension, and severe right-sided hydronephrosis, associated with ureteropelvic junction obstruction. Cytogenetic investigation revealed partial trisomy 3p; 46,XX,der(4)t(3;4) (p21.1;p16). The karyotype of her father showed a balanced translocation, t(3;4)(p21.1;p16). Therefore, the size of duplication can be an important factor.
3p部分三体综合征源于不平衡易位或新发重复。常见临床特征包括面部畸形、先天性心脏缺陷、精神运动和智力发育迟缓、肌张力异常以及生殖器发育不全。在本文中,我们报告了一例具有罕见临床表现的3p部分三体综合征病例。一名足月女新生儿被转诊至我们的诊所。她患有唇腭裂、胼胝体发育不全、动脉导管未闭、肺动脉高压以及严重的右侧肾积水,并伴有输尿管肾盂连接处梗阻。细胞遗传学检查显示为3p部分三体综合征;46,XX,der(4)t(3;4) (p21.1;p16)。其父亲的核型显示为平衡易位,t(3;4)(p21.1;p16)。因此,重复片段的大小可能是一个重要因素。
