Abstract
A terminal deletion of chromosome 3 at p25.3 was observed during prenatal diagnosis. A similar deletion is also present in the phenotypically normal mother. The deletion was confirmed by FISH. The breakpoint is distal to the region responsible for the 3p- syndrome. A normal baby girl was born with no apparent phenotypic abnormalities.
摘要
产前诊断期间观察到3号染色体p25.3处的末端缺失。在表型正常的母亲中也存在类似的缺失。通过荧光原位杂交（FISH）证实了该缺失。断点位于负责3p-综合征区域的远端。一名正常女婴出生，无明显表型异常。
