The goal of genetic testing for hereditary neurological diseases is to determine whether or not a patient has the disease, or is likely to develop it. Determining the molecular cause of a neurological disease can open the door to individually tailored treatment and medical care, and allow families to avoid invasive and often costly testing and procedures.

  • 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.
