Overview of Gene Research
YWHAE, also known as 14-3-3ε, is a gene located on chromosome 17p13.3. Its product, the 14-3-3epsilon protein, belongs to the 14-3-3 protein family. As a molecular scaffold, YWHAE participates in various biological processes such as cell adhesion, cell cycle regulation, signal transduction, and malignant transformation, and is involved in pathways like MAPK, NF-κB, and PI3K [2]. It is of great biological importance as it relates to numerous diseases [2]. Genetic models, especially mouse models, are valuable for studying YWHAE.
In a mouse knockout study of Ywhae, neuroanatomical studies revealed brain structural defects including thin cerebral cortex, corpus callosum dysgenesis, and hydrocephalus, paralleling the brain malformations seen in humans with YWHAE loss-of-function variants. These human cases showed manifestations like developmental delay, delayed speech, seizures, and brain malformations such as corpus callosum hypoplasia, delayed myelination, and ventricular dilatation, indicating that YWHAE loss-of-function causes a neurodevelopmental disease with brain abnormalities [1].
In conclusion, YWHAE is a crucial gene involved in multiple biological processes. The Ywhae knockout mouse model has been instrumental in revealing its role in neurodevelopmental diseases, specifically demonstrating that loss-of-function of YWHAE leads to brain abnormalities and associated neurological symptoms [1].
