Sialin

Scientific background:

Summary: The gene product is a lysosomal solute transport whose mutations cause sialic acid storage disease.

Test strategy: In patients whose predecessors come from Finland, screening for target mutations might be sufficient. But in the isolated cases that might occur world wide, analysing the whole gene is more appropriate.

Methodology:

 

clinical
test
Method Genomic sequencing of the entire coding region
Turn-around time 25 working days
Effort medium
Specimen DNA
Quality assessment Internal quality control only
  All known and new missense, nonsense and splice mutations can be detected.

 

clinical
test
Method Carrier testing
Turn-around time 5 working days
Effort little
Specimen DNA
Quality assessment Internal quality control only
  The test is only specific about the mutation already known in this kindred.
