概括

患有相同MEFV基因变异的儿科家族地中海热 (FMF) 兄弟姐妹在很大程度上表现出类似的症状,但疾病严重程度和关节炎患病率可能会因诊断延迟而有所不同.

科学领域:

遗传学遗传学是一个
儿科儿科儿科
类风湿病学类风湿病学

背景情况:

家庭地中海热 (FMF) 是一种自身炎症性疾病.
MEFV基因中的遗传变异是病因.
即使在基因相同的个体中,表型变异也存在.

研究的目的:

评估儿科 FMF 兄弟夫妇与相同的双外型 10 个 MEFV 变体的临床一致性和表型变异性.
调查导致观察到的临床差异的因素.

主要方法:

对来自95个家庭的190个儿科FMF非双胞胎兄弟姐妹进行横截面研究.
对人口统计数据,临床表现,疾病严重程度得分 (Pras,ISSF) 和素反应的分析.
追溯的数据收集.

主要成果:

41%的兄弟姐妹对在临床特征上表现出完全一致;79%的科尔奇辛反应匹配.
年长的兄弟姐妹有更长的诊断延迟和更高的Pras分数.
关节炎在年长的兄弟姐妹中比较常见 (30%对13%).

结论:

在FMF兄弟姐妹中,相同的MEFV基因型导致基本一致的主要临床特征.
疾病严重程度和关节炎患病率的差异可能是由于诊断延迟和与年龄相关的进化,而不是内在的遗传差异.

Complementation Tests

Complementation Tests

A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...
