Novel SCN1A and GABRA1 Gene Mutations With Diverse Phenotypic Features and the Question on the Existence of a Broader Spectrum of Dravet Syndrome
In the light of modern molecular technologies, the understanding of the complexity of the numerous genotype-phenotype correlations regarding Dravet syndrome is mandatory. Motivated by 2 patients, whose whole-exome sequencing revealed novel mutations that exemplify the phenotypic and genetic heterogeneities associated with typical and atypical Dravet syndrome presentations, the authors discuss t...
متن کاملPhenotypic spectrum of FARS2-deficiency
We read with interest the article by Vantroys et al. about two unrelated pediatric patients with FARS2-deficiency [1]. We have the following comments and concerns. Insomnia is a rare manifestation of a mitochondrial disorder(MID). Only in a study of 20 CPEO patients, 75% reported sleep dysfunction [2]. Did patient-2 take drugs that could explain sleeplessness? What were the results on polysomno...
متن کاملDelineating the GRIN1 phenotypic spectrum
OBJECTIVE To determine the phenotypic spectrum caused by mutations in GRIN1 encoding the NMDA receptor subunit GluN1 and to investigate their underlying functional pathophysiology. METHODS We collected molecular and clinical data from several diagnostic and research cohorts. Functional consequences of GRIN1 mutations were investigated in Xenopus laevis oocytes. RESULTS We identified heteroz...
متن کاملPseudohypoparathyroidism: phenotypic spectrum in kindred
Pseudohypoparathyroidism (PHP) encompasses a heterogeneous group of disorders due to an inactivating mutation in the GNAS gene which encodes the a subunit of Gs proteins (Gsa). Gsa plays a crucial role in intracellular signal transduction of peptides, hormones and neurotransmitter receptors in multiple tissues. Key features of PHP include Albright Hereditary Osteodystrophy (AHO) and biochemical...
متن کاملThe phenotypic spectrum of SCN8A encephalopathy.
OBJECTIVE SCN8A encodes the sodium channel voltage-gated α8-subunit (Nav1.6). SCN8A mutations have recently been associated with epilepsy and neurodevelopmental disorders. We aimed to delineate the phenotype associated with SCN8A mutations. METHODS We used high-throughput sequence analysis of the SCN8A gene in 683 patients with a range of epileptic encephalopathies. In addition, we ascertaine...
