Clear diagnosis with genetic testing is the basis of effective treatment and management for many disorders of the brain and nervous system. Serving as an invaluable tool, genetic testing enables the identification of inherited neurological conditions, such as muscle control and movement disorders, delayed mental development, degeneracy and learning disabilities. With knowledge of variants associated with neurological diseases in more than 1,850 genes, our vast knowledge and diagnostic expertise can help you diagnose your patients quickly and comprehensively.

Recurrent Null Mutation in SPG20
Troyer syndrome is an autosomal recessive form of complex hereditary spastic paraplegia. To date, the disorder has only been described in the Amish and in kindred from Oman. In Amish, all affected individuals have a homozygous one nucleotide deletion; c.1110delA. In the Omani kindred, all affected…

Functional and Clinical Consequences of Novel α-Galactosidase A Mutations in Fabry Disease
Fabry disease (FD) is a rare metabolic disorder of glycosphingolipid storage caused by mutations in the GLA gene encoding lysosomal hydrolase α-galactosidase A (α-gal A). We conclude that a mild GLA variant is typically characterized by high residual enzyme activity and normal biomarker levels. We…

TALPID3 Controls Centrosome
Joubert syndrome (JBTS) is a severe recessive neurodevelopmental ciliopathy which can affect several organ systems. Mutations in known JBTS genes account for approximately half of the cases. By homozygosity mapping and whole-exome sequencing, we identified a novel locus, JBTS23, with a homozygous…

TuScCom – Biomarker for Tuberous Sclerosis Complex
Tuberous sclerosis complex (TSC) is a genetic disorder that causes non-malignant tumors to form in many different organs, primarily in the brain, eyes, heart, kidney, skin and lungs. The aspects of TSC that most strongly impact quality of life are generally associated with the brain: seizures,…

Asparagine Synthetase Deficiency: New Inborn Errors of Metabolism
Asparagine synthetase deficiency (ASD) is a newly identified neurometabolic disorder characterized by severe congenital microcephaly, severe global developmental delay, intractable seizure disorder, and spastic quadriplegia.
