在威尔士东南部(人口668,100)进行的一项基于人群的von Recklinghausen神经纤维瘤病研究确定了69个家庭,135名受影响成员(患病率为1/4950)。在这些家庭中,NF-1基因在5岁时的突变率为100%。NF-1患者的遗传适合度降低到0.47,男性比女性的影响更明显(分别为f = 0.31和0.60)。135例病例中有41例被判定为代表新的疾病突变,突变率估计在3.1 × 10(-5)和10.4 × 10(-5)之间。没有发现新突变的父母年龄效应,也没有发现母亲对疾病严重程度的影响。
A population based study of von Recklinghausen neurofibromatosis in south east Wales (population 668,100) identified 69 families with 135 affected members (prevalence 1/4950 of the population). In these families penetrance of the NF-1 gene was 100% by the age of five years. The genetic fitness of NF-1 sufferers was found to be reduced to 0.47, the effect being more marked in males than females (f = 0.31 and 0.60, respectively). Forty-one of 135 cases were judged to represent new disease mutations and the mutation rate was estimated to lie between 3.1 x 10(-5) and 10.4 x 10(-5). A parental age effect for new mutations was not found, nor was a maternal effect on disease severity.
