ALG13 Gene Glycosylation Disorder Type 1S NGS Genetic DNA Test
Comprehensive Introduction to ALG13 Genetic Testing
The ALG13 Gene Glycosylation Disorder Type 1S NGS Genetic DNA Test represents a breakthrough in metabolic disorder diagnostics, offering precise identification of genetic mutations responsible for congenital disorders of glycosylation. This advanced testing methodology utilizes next-generation sequencing technology to examine the ALG13 gene, which plays a critical role in the complex biochemical process of protein glycosylation. When this essential cellular function becomes disrupted, it can lead to severe metabolic complications affecting multiple organ systems throughout the body.
Glycosylation disorders represent a group of rare inherited metabolic conditions where the addition of sugar molecules to proteins becomes impaired. The ALG13 gene specifically encodes an enzyme involved in the dolichol-linked oligosaccharide pathway, which is fundamental for proper protein folding and cellular communication. Understanding your genetic profile through this test provides invaluable insights for managing metabolic health and preventing potential complications.
What This Advanced Genetic Test Detects
The ALG13 Gene Glycosylation Disorder Type 1S NGS Genetic DNA Test specifically identifies:
- Pathogenic variants in the ALG13 gene located on chromosome X
- Mutations affecting the ALG13 alpha-1,3-glucosyltransferase enzyme function
- Genetic alterations that disrupt the N-linked glycosylation pathway
- Inheritance patterns including X-linked dominant transmission
- Specific nucleotide changes impacting enzyme catalytic activity
This comprehensive analysis examines the entire coding region of the ALG13 gene, detecting single nucleotide variants, small insertions and deletions, and copy number variations that could contribute to glycosylation disorder type 1S manifestations.
Who Should Consider ALG13 Genetic Testing
Clinical Indications and Symptoms
This genetic test is particularly recommended for individuals presenting with:
- Unexplained developmental delays in infancy or early childhood
- Neurological symptoms including seizures, hypotonia, or movement disorders
- Failure to thrive despite adequate nutritional intake
- Hepatic dysfunction or abnormal liver enzyme levels
- Coagulation abnormalities and bleeding tendencies
- Ocular abnormalities including strabismus or nystagmus
- Family history of metabolic disorders or unexplained infant mortality
- Abnormal transferrin glycosylation patterns in previous testing
Special Considerations
Genetic counseling is strongly recommended before testing, particularly for families with:
- Multiple affected family members across generations
- Unexplained neonatal or infant deaths
- Consanguineous parental relationships
- Previous children with developmental regression

Understanding Your Genetic Test Results
Interpretation Guidelines
Your ALG13 genetic test results will fall into one of several categories:
Positive Result
A positive result indicates the presence of a pathogenic variant in the ALG13 gene consistent with glycosylation disorder type 1S. This confirmation enables:
- Implementation of specific metabolic management protocols
- Regular monitoring for known complications
- Family genetic testing and counseling
- Connection with specialized metabolic treatment centers
Negative Result
A negative result suggests that no pathogenic variants were detected in the ALG13 gene. However, this does not completely exclude:
- Other genetic causes of glycosylation disorders
- Technical limitations of current testing methodologies
- Variants in regulatory regions not covered by the test
- Mosaic mutations present in limited tissue types
Variant of Uncertain Significance (VUS)
Some genetic changes may be classified as variants of uncertain significance, requiring:
- Additional family studies for segregation analysis
- Functional studies to determine pathogenicity
- Periodic reclassification as new evidence emerges
- Careful correlation with clinical presentation
