The ST3GAL5 gene is responsible for the synthesis of the CMP-NeuAc:LacCer α-2,3-sialyltransferase enzyme, which plays a crucial role in the modification of gangliosides. Gangliosides are a type of glycosphingolipid found in cell membranes, particularly in nerve cells. These complex molecules are involved in cell signaling and are crucial for normal brain development and function.
Changes in the ST3GAL5 gene can lead to the deficiency of this enzyme, resulting in a condition known as ST3GAL5-related disorders. This deficiency can affect the synthesis of specific gangliosides, such as GM3 and CMP-NeuAcLacCer, leading to a variety of diseases and conditions.
ST3GAL5-related disorders are often characterized by neurological symptoms, including intellectual disability, developmental delay, and seizures. Additional symptoms may include facial dysmorphism, skeletal abnormalities, and impaired vision. The severity and specific features of ST3GAL5-related disorders can vary widely between affected individuals, and the genetic changes responsible for these disorders may also differ.
Diagnosis of ST3GAL5-related disorders usually involves genetic testing to identify changes or variants in the ST3GAL5 gene. This testing can be done through various genetic testing resources, such as OMIM, PubMed, and other related databases. However, it is important to note that the genetic changes associated with ST3GAL5-related disorders may not always be fully understood, and further research is needed to clarify the precise mechanisms involved.
Understanding the genes and genetic changes involved in ST3GAL5-related disorders is crucial for diagnosis, treatment, and management of affected individuals. Genetic testing can help provide valuable information for healthcare professionals and families, enabling personalized care and support. It can also contribute to further scientific research and advancements in the field of genetics and related health conditions.

GM3 synthase deficiency
GM3 synthase deficiency, also known as ST3GAL5 gene deficiency, is a rare genetic condition characterized by the lack of the GM3 synthase enzyme. This enzyme is responsible for the synthesis of GM3 ganglioside, a complex lipid molecule found in cell membranes.
Individuals with GM3 synthase deficiency usually experience neurological symptoms, such as developmental delays, intellectual disability, seizures, and movement disorders. Other symptoms may include drowsiness, muscle weakness, and abnormal muscle tone.
GM3 synthase deficiency is inherited in an autosomal recessive manner, which means that both copies of the ST3GAL5 gene must be mutated to develop the condition. Genetic testing can confirm the diagnosis by identifying mutations in the ST3GAL5 gene.
Currently, there is no cure for GM3 synthase deficiency. Treatment options aim to manage the symptoms and may include physical therapy, occupational therapy, and medications to control seizures or movement disorders.
More information about GM3 synthase deficiency can be found in the OMIM database (Online Mendelian Inheritance in Man) or through other scientific resources. These resources provide additional information on genetic conditions, genes, and related health changes.
