概括

哈雷金病 (Harlequin ichthyosis,简称IF) 是一种严重的皮肤病,现在已经在家猫身上被描述. 基因分析显示,ABCA12基因发生突变,导致小猫患上这种罕见疾病.

科学领域:

兽医遗传学兽医遗传学
皮肤病学皮肤病学
遗传性疾病遗传性疾病

背景情况:

胎儿性 Ichthyosis (IF),也称为哈雷金式 Ichthyosis,是一种罕见的,严重的,往往致命的先天性皮肤疾病.
皮肤加厚,裂和形的特征,IF损害了皮肤屏障,导致危及生命的感染.
之前没有在家猫身上描述过FI.

研究的目的:

在两个国内短发 (DSH) littermates中描述IF的临床,本病理和遗传特征.
在受影响的猫新生儿中确定IF的遗传基础.

主要方法:

对受影响的DSH小猫进行总体临床检查和组织病理学分析.
整个基因组测序和种群基因定型在受影响的小猫和对照猫类样本上进行.

主要成果:

临床和组织病理学发现证实了两只受影响的小猫的IF.
在ABCA12基因中发现了同卵性的一基对缺失,导致框架转移和预测的蛋白质功能丧失.
所有140只对照猫对野生类型的ABCA12等位基因均为同卵性.

结论:

这项研究提供了第一份关于家猫中胎儿 Ichthyosis fetalis 的描述.
在这些猫类病例中,致病性ABCA12位变异被确定为IF的可能遗传原因.
已知ABCA12变种是人类,牛和小鼠中IF的已知原因,突出显示了跨物种保存的遗传机制.

X-Inactivation

X-Inactivation

The human X chromosome contains over ten times the number of genes as in the Y chromosome. Since males have only one X chromosome, and females have two, one might expect females to produce twice as many of the proteins, with undesirable results.

Point and Frameshift Mutations

Point and Frameshift Mutations

Point mutations are genetic alterations involving the change of a single nucleotide base pair in DNA. Depending on how the alteration affects protein synthesis, they can lead to various consequences.Point mutations fall into the following types:Silent mutations occur when a nucleotide change does not alter the amino acid sequence due to the redundancy of the genetic code. For instance, changing ACC to ACA still encodes threonine, leaving the protein function unaffected. This occurs because...
