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.

Novel GNB1 Mutations Disrupt Assembly and Function of G Protein Heterotrimers and Cause Global Developmental Delay in Humans
Global developmental delay (GDD), often accompanied by intellectual disability, seizures and other features is a severe, clinically and genetically highly heterogeneous childhood-onset disorder. In cases where genetic causes have been identified, de-novo mutations in neuronally expressed genes are…
Duchenne muscular dystrophy (DMD) is a rare muscle disorder but it is one of the most frequent genetic conditions affecting approximately 1 in 3,500 male births worldwide. The goal of this study is to identify and validate a new biochemical marker from the plasma of affected patients helping to…
Novel GNB1 Missense Mutation in a Patient with Generalized Dystonia, Hypotonia, and Intellectual Disability
Recently, exome sequencing has extended our knowledge of genetic causes of developmental delay through identification of de novo, germline mutations in the guanine nucleotide-binding protein, beta 1 (GNB1) in 13 patients with neurodevelopmental disability and a wide range of additional symptoms and…
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…
