Mutations of the SPAST gene, which encodes microtubule-severing protein spastin, are most common cause hereditary spastic paraplegia (HSP). Haploinsufficiency is prevalent opinion as to mechanism disease, but gain-of-function toxicity mutant proteins another possibility. Here, we report a new transgenic mouse (termed SPASTC448Y mouse) that not haploinsufficient expresses human spastin bearing HSP pathogenic C448Y mutation. Expression was documented from fetus adult, gait defects reminiscent...
Amyotrophic lateral sclerosis (ALS) is a multi-system disease characterized primarily by progressive muscle weakness. Cognitive dysfunction commonly observed in patients; however, factors influencing risk for cognitive remain elusive. Using sparse canonical correlation analysis (sCCA), an unsupervised machine-learning technique, we that single nucleotide polymorphisms collectively associate with baseline performance large ALS patient cohort (N = 327) from the multicenter Clinical Research...
As broad genetic testing (multi-gene panels, exome sequencing, and genome sequencing) is increasingly common, a growing number of individuals have been identified with variants unknown significance (VUSs) in medically actionable genes, including those associated inherited connective tissue disorders (ICTDs). These ICTDs include vascular Ehlers Danlos syndrome (vEDS), Loeys Dietz (LDS) Marfan (MFS). Our ICTD clinic has evaluated more than 100 such the past 5 years. Medical geneticists...
In the precision medicine era, genetic diagnoses direct clinical management and lead to improved health outcomes. However, there is scant data on role of race or social determinants (SDH) in access medical genetics evaluation outcomes testing general adult population. This study examines whether race, ethnicity, measures SDH influence results
Abstract Amyotrophic lateral sclerosis (ALS) is a multi-system disease characterized primarily by progressive muscle weakness.

Amyotrophic lateral sclerosis (ALS) is the most common degenerative motor neuron disorder. Although cases of ALS are sporadic, 5–10% familial, with mutations associated over 40 genes. There variation symptoms within families carrying same mutation; disease may develop in one sibling and not another despite presence mutation both. cause this phenotypic unknown, it likely related to genetic modifiers expression. The identification causing genes has led development transgenic mouse models...
