Pcr - based analysis method was carried out in the following study . dna amplification by pcr in cgg repeats were performed on 154 people as normal control ( 73 males and 81 females ) and 23 members from four x - linked mental retardation ( xlmr ) families . after electrophoresed on a 6 % - denaturing polyacrylamide gel ( acr : bis = 19 : l ) , genotypes of the objects were determined by analyzing pcr products 本研究采用較以往更為簡(jiǎn)便有效的pcr技術(shù)方法,對(duì)隨機(jī)抽取的154人的正常群體(男性73人、女性sl人)及來(lái)自四個(gè)智力低下家系的23名成員進(jìn)行了fmr基因cgg重復(fù)序列的擴(kuò)增,利用變性聚丙烯酸胺凝膠電泳技術(shù)對(duì)不同等位基因類型進(jìn)行分離和統(tǒng)計(jì)。
Fxs is characterized by x - linked mental retardation with additional features such as a long face with large protruding ears , macroorchidism , and eye - gaze avoidance etc . fxs is associated with a fragile site , designated fraxa ( fragile site , x chromosome , a site ) , at xq27 . 3 near the end of the long arm 其主要臨床特征為智力低下、特殊的外貌特征(包括長(zhǎng)臉、大耳廓、下頜突出、巨頭、腭弓高、大睪丸等) 、行為及認(rèn)知障礙、多動(dòng)、注意力難集中以及孤獨(dú)、自閉等癥狀。
X-linked mental retardation (also known as X-linked intellectual disability) refers to forms of mental retardation which are specifically associated with X-linked recessive inheritance.
