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,...

Exon Recombination

Exon Recombination

The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon has three reading...

Nonsense-mediated mRNA Decay

Nonsense-mediated mRNA Decay

The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Genomic Imprinting and Inheritance

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Background:

Hearing loss is a prevalent sensory disorder, affecting 1 in 500 newborns.
Nonsyndromic hearing loss is genetically heterogeneous, with 46 identified causative genes.
Understanding these genes is crucial for diagnosing and potentially treating hearing impairment.

Purpose of the Study:

To provide a comprehensive overview of genes causing nonsyndromic hearing loss.
To detail the inner ear function and expression patterns of these identified genes.
To update knowledge on genes involved in hair bundle morphogenesis, including nonsyndromic and Usher syndrome genes.

Main Methods:

Literature review of identified nonsyndromic hearing loss genes.
Analysis of gene functions related to hair bundle morphogenesis, extracellular matrix, ion homeostasis, and transcription factors.
Summarization of gene expression patterns and functional impacts on hearing.

Main Results:

Identified 46 genes associated with nonsyndromic hearing loss.
Detailed the roles of these genes in hair bundle morphogenesis, extracellular matrix, ion homeostasis, and transcription.
Compiled a table of gene-specific cochlear expression patterns by cell type.

Conclusions:

Significant advancements have been made in understanding genes involved in hair bundle morphogenesis.
The review consolidates essential information on nonsyndromic deafness genes for auditory scientists.
Expression patterns and functional impacts are critical for understanding hereditary hearing loss.
