分子心脏病学分子心脏病学
遗传流行病学遗传流行病学

背景情况:

PLN p.(Arg14del) 是一种已知的与心脏病相关的遗传变异.
在这些患者中,额外的罕见遗传变异的临床意义尚未完全理解.
了解这些变异可以改善风险分层和患者管理.

研究的目的:

确定PLN p.(Arg14del) 患者心肌病和通道病相关基因中其他罕见遗传变异的流行率.
评估这些额外变异的临床后果,重点关注恶性心室节律失常 (MVA) 和严重心力衰竭 (HF).

主要方法:

收集了160名 PLN p. ((Arg14del) 指数患者中其他罕见遗传变异的数据.
分类变种为具有不确定的意义 (VUS) 或 (可能) 致病性 (L) P) 的变种.
在有或没有额外的 (L) P变异的患者中比较了MVA或严重的HF事件的发生和发病率.

主要成果:

在6%的PLN指数患者中发现了额外的 (L) P变异.
患有额外 (L) P变异的患者表现出较早MVA或严重HF事件的非显著趋势.
在亲属的级联测试中,在45岁之前发生重大心脏病事件的8个人中,有2个人发现了额外的致病变体.

结论:

额外的 (L) P变异在 PLN p. ((Arg14del) 患者中比对照人群更为普遍.
这些变异可能与MVA或HF相关症状的早期发病有关.
需要进一步的研究,以充分阐明这些遗传发现的影响.

Pleiotropy

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
