Summary
Researchers identified gene variants causing hereditary hearing loss in Pakistani children. This study advances understanding of non-syndromic hearing loss (NSHL) genetics and aids potential genetic screening efforts.
Area of Science:
- Genetics
- Audiology
- Molecular Biology
Background:
- Hearing loss is a complex disorder with diverse genetic causes.
- Over 117 genes are linked to hereditary, nonsyndromic hearing loss (NSHL).
- Identifying population-specific gene variants is crucial for public health and genetic screening.
Purpose of the Study:
- To identify gene variants responsible for NSHL in a Pakistani cohort.
- To contribute to the genetic understanding of hearing impairment in diverse populations.
Main Methods:
- Screened 40 Pakistani children with NSHL for GJB2 variants.
- Utilized targeted next-generation sequencing (TNGS) for variant identification.
- Analyzed variants in 15 distinct genes associated with hearing loss.
Main Results:
- Identified known GJB2 variants in 15 individuals.
- Discovered 20 different variants across 14 genes in the remaining participants.
- Reported common and novel variants in 15 genes within the Pakistani NSHL cohort.
Conclusions:
- Successfully identified common and novel gene variants in a Pakistani NSHL cohort.
- The findings expand the known genetic landscape of NSHL.
- This research supports the development of genetic diagnostic tools for hearing loss.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

01:12Loss of Tumor Suppressor Gene Functions
5.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

5.0K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

517
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.

370
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...
