概括

具有1个FGF4L2基因副本的 Dachshunds 具有较少的化磁盘,从而降低脊髓疾病的风险. 繁殖一个FGF4L2副本是改善大背脊健康的实际目标.

科学领域:

兽医遗传学兽医遗传学
狗的健康狗的健康
整形外科的研究研究.

背景情况:

狗椎间盘疾病 (IVDD) 的遗传基础是复杂的.
FGF4L2基因拷贝数变异与脊柱状况有关.
有限的数据存在于FGF4L2基因型和犬的放射性磁盘化.

研究的目的:

为了研究FGF4L2基因型与犬的放射性磁盘化得分 (K-n) 之间的关联.
为了确定FGF4L2复制号是否会影响脊髓疾病的风险.
为了告知育种策略,以改善大的脊柱健康.

主要方法:

对来自挪威和芬兰 kennel 俱乐部的 407 条大白进行了回顾性分析.
基于K-n分数和FGF4L2基因型 (0,1或2个副本) 的狗的分类.
使用Cochran-Mantel-Haenszel测试进行统计分析,以比较跨基因型的K-n分布.

主要成果:

在具有0个和2个FGF4L2副本的犬之间观察到K-n分布的显著差异.
在具有1个和2个FGF4L2副本的犬之间,没有发现K-n分布的显著差异.
具有1个FGF4L2副本的狗的K-n分数与0个副本的狗相似.

结论:

具有一个FGF4L2副本的犬表现出较低的放射性磁盘化,这表明症状性磁盘疾病的风险降低.
旨在改善大的脊椎健康的繁殖计划应该考虑针对一个FGF4L2副本,因为它具有很高的等位基因频率.
建议对K-n分数和FGF4L2基因型进行评估,以选择大犬繁殖种群.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
