Abstract:
In the presented case of familial mitral valve prolapse, whole exome sequencing was used to reveal a missense variant in the PDLIM7 gene. This gene is considered a possible novel candidate gene for familial MVP based on PDLIM7 knock-out mice and zebrafish showing mitral valve abnormalities.
Insights
Whole exome sequencing identified a PDLIM7 gene variant in familial mitral valve prolapse. This finding suggests PDLIM7 as a potential novel gene linked to mitral valve prolapse (MVP) inheritance.
Area of Science:
- Genetics
- Cardiovascular Medicine
- Molecular Biology
Background:
- Familial mitral valve prolapse (MVP) is a heart condition with a significant genetic component.
- Identifying the specific genes responsible for familial MVP is crucial for understanding disease mechanisms and developing targeted therapies.
Purpose of the Study:
- To investigate the genetic basis of familial mitral valve prolapse (MVP) in a specific case.
- To identify potential novel candidate genes associated with MVP.
Main Methods:
- Whole exome sequencing (WES) was employed to analyze the genetic makeup of individuals with familial MVP.
- Bioinformatic analysis was used to identify variants within coding regions of the genome.
Main Results:
- A missense variant in the PDLIM7 gene was identified in the familial MVP case.
- Previous studies using PDLIM7 knockout models in mice and zebrafish demonstrated mitral valve abnormalities, supporting the relevance of this gene.
Conclusions:
- The PDLIM7 gene is proposed as a novel candidate gene for familial mitral valve prolapse (MVP).
- Further research into PDLIM7's role in cardiac development and function is warranted to confirm its association with MVP.

01:31Adrenergic Receptors: ɑ Subtype
1.3K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

2.9K
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

01:11Ammeter
2.0K
An ammeter is a current measuring instrument. In the circuit, it is represented by the symbol A. The ammeter is placed in series with the device or component to measure the current. A series connection is used because objects in series have the same current passing through them. If a circuit has multiple resistors and the current needs to be measured in each resistor, the number of ammeters required depends on whether the circuit is in series or parallel.

01:14The Aorta
542
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

01:11Aryldiazonium Salts to Azo Dyes: Diazo Coupling
2.9K
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the...

3.8K
Direct alkylation of ammonia produces polyalkylated amines, along with a quaternary ammonium salt. To exclusively prepare primary amines, the azide synthesis method can be used.
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
