OBJECTIVE To identify the etiology of a novel, heritable encephalopathy in a small group of patients. METHODS Magnetic resonance imaging (MRI) pattern analysis was used to select patients with the same pattern. Homozygosity mapping and whole exome sequencing (WES) were performed to find the causal gene mutations. RESULTS Seven patients from 4 families(More)
We describe a family with QARS deficiency due to compound heterozygous QARS mutations, including c.1387G > A (p.R463*) in the catalytic core domain and c.2226C > G (p.Q742H) in the anticodon domain, both previously unreported and predicted damaging. The phenotype of the male index further confirms this specific aminoacyl-transfer RNA (tRNA) synthetase(More)
Glutaminyl-tRNA synthetase (QARS) deficiency has been described to be a cause of a neurodegenerative disorder associated with severe developmental delay, microcephaly, delayed myelination, and intractable epilepsy. The epilepsy is thought to be more severe than other tRNA synthetase disorders. Only a few cases have been reported in the literature and there(More)
