안면기형 없는 경한 임상증상을 보인 14번 환상염색체 증후군 1례.

The characteristic features of ring chromosome 14 syndrome are microcephaly, facial dysmorphism, ocular abnormalities, psychomotor retardation, and drugresistant epilepsy. Here, we report the case of a 2-year-old girl, diagnosed with ring 14 syndrome with mild clinical features. The child had microcephaly without facial dysmorphism, a slight language delay, and well-controlled seizures with a favorable progress. Her first seizure occurred at the age of 4 months and she has been seizurefree for 12 months since turning 3 years old. She exhibited only a mild language delay, which is still improving. It is important to note that ring chromosome 14 may manifest as early onset seizures with mild psychomotor delay, but without facial dysmorphism. These patients may follow a favorable clinical course. [ABSTRACT FROM AUTHOR]
