摘要


第10對染色體長臂遠端的部份單染色體是一種不常見的染色體異常,主要監床特徵包括:生長遲緩、心智發育遲緩、顏面異常、先天性心臟、肛門生殖器、泌尿道異常。本文報告一女童在4個月時診斷為de novo的第10對染色體長臂的遠端缺失,其斷點在10q26,在心智發展評估後,發現病患只有輕微發展遲緩。並回顧探討相關文獻。

並列摘要


Partial monosomy of distal l0q is an uncommon chromosomal disorder Its characteristic features include growth retardation, psychomotor delay, facial dysmorphia, congenital heart disease, and anogenital/urinary tract anomalies. Reported here is a female infant at age 4 months who was diagnosed with a de novo deletion of the long arm of chromsome 10, with a breakpoint at l0q26. Using the Bayley scales of infant development II, she was found to have mild psychomotor delay. We also review the related literature of partial deletion of the long arm of chromosome 10.
