The SRD5A3 gene encodes an enzyme that plays a crucial role in the production of a sugar called dolichol. Dolichol is involved in the glycosylation process, which is essential for the proper functioning of many proteins in the body. Mutations in the SRD5A3 gene can lead to a condition known as SRD5A3-congenital disorders of glycosylation (SRD5A3-CDG).

SRD5A3-CDG is a rare genetic disorder that affects various organs and systems in the body. It can cause a range of health changes, including developmental delays, intellectual disability, facial dysmorphism, and abnormalities in the brain, eyes, liver, and other organs. The disorder is inherited in an autosomal recessive manner, meaning that both copies of the SRD5A3 gene must be mutated for the condition to occur.

Information about SRD5A3 gene mutations and their associated clinical features can be found in databases such as OMIM (Online Mendelian Inheritance in Man) and the Genetic Testing Registry. Additional names for this disorder include retinal dystrophy, intellectual disability, and epilepsy (RDID syndrome) and congenital disorder of glycosylation type Iq (CDG-Iq).

References to articles and other scientific resources related to SRD5A3 gene and SRD5A3-CDG can be found on PubMed and in the Genet CATALOG. The Lefeber Lab at Radboud University Medical Center in the Netherlands also provides information on this condition, including testing resources and a registry for affected individuals.

Genetic changes in the SRD5A3 gene are associated with several health conditions and diseases. These changes can affect the production of the enzyme dolichol-phosphate mannose synthase, leading to impaired glycosylation. Glycosylation is a process by which sugar molecules are attached to proteins and lipids, and it plays a vital role in the function of many proteins in the body.

One health condition related to genetic changes in the SRD5A3 gene is SRD5A3-congenital disorder of glycosylation (SRD5A3-CDG). This rare disorder is characterized by developmental delay, intellectual disability, and other neurological symptoms. It can also cause abnormalities in facial features, as well as heart, liver, and kidney problems.

Patients, too, are unhappy with the care they receive during those brief interactions with their doctors. Healthcare communications company West Corporation reported that 25% of patients don’t feel that their provider cares about them as an individual and nearly 20% aren’t convinced their doctor is focused on improving their health – even though 93% of doctors strongly agree that patient satisfaction is important.

To diagnose SRD5A3-CDG, genetic testing is typically performed. This testing examines the SRD5A3 gene for specific variants associated with the disorder. Genetic testing can be conducted using a variety of resources, including databases such as OMIM and the Human Gene Mutation Database (HGMD).

Diagnostic laboratories may also offer specific tests for SRD5A3-CDG, which can detect changes in the SRD5A3 gene. These tests typically involve sequencing the gene to identify any genetic variants.

In addition to SRD5A3-CDG, changes in the SRD5A3 gene have been associated with other health conditions. For example, a variant in this gene has been reported in individuals with retinal dystrophy, a group of genetic disorders that affect the retina and can cause progressive vision loss.

Further scientific research is needed to fully understand the impact of SRD5A3 gene changes on health and the development of specific conditions. Additionally, studies are ongoing to explore potential targeted treatments for conditions associated with SRD5A3 gene variants.
