Molecular Genetic Pathology, Molecular Microbiology Division
The Molecular Genetic Pathology Lab performs the following testing:
- Fragile X Syndrome: Polymerase chain reaction for accurate sizing of FMR1 allele size; methylation status of permutation and full mutation alleles is also performed.
- Prader-Willi/Angelman Syndrome: Assessment of the methylation status of the 15q11 locus using pyrosequencing technology for sequence-based detection and quantification of the maternal and paternal alleles.
- Cytogenomic SNP Arrays: Cytoscan HD Assay is a qualitative assay intended for the postnatal detection of chromosomal copy number variants (CNV) associated with developmental delay and/or intellectual disability (DD/ID), congenital anomalies, and/or dysmorphic features.
- This department plans to offer very soon Sanger sequencing for the detection of familial variants and the diagnosis of single gene disorders, Next Generation Sequencing panels for DD/ID, autism, neurology, cardiology, pulmonology, congenital anomalies and more complex indications.
