This study was designed to test for the fragile X syndrome [fra(X)] in institutionalized male patients with nonspecific mental retardation, referral patients, and relatives of fra(X) patients. Thirty-one of 91 (34.0 per cent) subjects tested were positive for the fra(X) chromosome; relatives had the largest percentage of positives. The data reflect the value of this test for detecting families having potential carriers who can benefit from genetic counseling.
本研究旨在检测收容机构中患有非特异性智力迟钝的男性患者、转诊患者以及脆性X综合征(fra(X))患者亲属中的脆性X综合征[fra(X)]。91名受试对象中有31名(34.0%)fra(X)染色体检测呈阳性;亲属中的阳性比例最高。这些数据反映了该检测对于发现那些可从遗传咨询中受益的潜在携带者家庭的价值。
