We describe a male child with craniofacial anomalies, postnatal onset growth retardation, microcephaly, multiple minor anomalies, hearing loss, and moderate delay of mental and statomotor development. He carries a previously undescribed tandem translocation between the long arm of chromosome 14 and the short arm of chromosome 21 that arose de novo. As proven by fluorescence in situ hybridization a microdeletion not detectable with high-resolution G-banding occured in 14q32.3, the terminal band on the long arm of chromosome 14. The resulting phenotype includes most abnormalities encountered in patients with terminal 14q32.3 deletions but in addition includes some characteristics of the ring chromosome 14 syndrome.
我们描述了一名患有颅面畸形、出生后生长发育迟缓、小头畸形、多发轻微畸形、听力丧失以及精神和运动发育中度延迟的男童。他携带一种先前未描述的14号染色体长臂与21号染色体短臂之间的串联易位,该易位为新发。荧光原位杂交证实,在14号染色体长臂末端带14q32.3处发生了高分辨率G显带无法检测到的微缺失。所产生的表型包括14q32.3末端缺失患者中出现的大多数异常情况,但此外还包括14号环状染色体综合征的一些特征。
