Low density lipoprotein receptor-related protein 2

Scientific background:

Summary: Mutations in LRP2 gene cause autosomal recessive Donnai-Barrow syndrome (DBS) and facio-oculoacoustico-renal syndrome (FOAR).

Methodology:

 

clinical
test
Method Genomic sequencing of the entire coding region
Turn-around time 25 working days
Effort large
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.
