|---|---|---|---|
| 설명 | 사람의 46개 염색체 중 제 21번 염색체의 수가 1개 더 많아지므로써 나타나는 병이다. 환자의 생김새가 마치 몽고 사람과 닮았다 하여 일명 몽고증(mongolism)이라고 하였으나 잘못된 이름이다. 이 병은 반드시 21번 염색체가 3개가 되는 경우이외에도 21번 염색체의 일부분이 다른 염색체의 일부분과 교환이 되는 translocation형 등의 다른 염색체이상에서도 볼 수가 있다. 발생 빈도는 출생아 700~1000명중 1명 꼴로 나타나며, 염색체 이상병 중에 가장 많은 것으로 알려져 있다. 이 병의 발생빈도는 산모의 출산연령과 밀접한 관계가 있어, 35세 이후가 되면 기하 급수적으로 이 질환자의 출산수가 증가한다. 일반적으로 이 질환에 있어서 약 3분의 1은 모친의 출산연령에 의존하지 않고, 나머지 약 3분의 2는 모친의 연령과 직접 관련이 있는 것으로 보고 있다. 진단은 특징적인 생김새, 즉 몽고 사람같이 눈꼬리가 위로 치켜져 있고 눈거풀이 두꺼우며 콧등이 낮은 특징적인 얼굴 모습, 또한 근육의 긴장도가 저하되고 젖을 빠는 힘과 울음 소리가 약하며 손바닥의 좌우를 가르는 한줄의 손금(원숭이와 같은 형태이다) 등의 특징적인 소견에 의해 보조진단을 하고 최종적으로 염색체 분석에 의해 확진을 한다. 이 다운증후군의 환자는 대개 지능이 저하되어 있고, 여러 가지 종류의 선천성 심장기형을 많이 동반하고 있다. |

| syndrome, down | A common disorder due to a chromosome abnormality and specfically due to an extra chromosome number 21 (trisomy 21). Down syndrome includes mental retardation, a characteristic face, and multiple malformations. It is associated with a major risk for heart problems, a lesser risk of duodenal atresia (part of the intestines not developed), and a minor but still significant risk of acute leukaemia. The name down syndrome comes from the 19th century english doctor langdon down, a misnomer since he was curiously enough not the first person to describe the condition and, in great error, attributed the condition to a reversion to the mongoloid race. Hence, the old name mongolism, now considered slang. (12 Dec 1998) |
