Dravet syndrome is caused by loss-of-function mutations in the SCN1A gene, which codes for the alpha subunit of the NaV1.1 sodium channel. However, there are other sodium channels, and it is known that gain-of-function mutations in SCN8A, the gene that codes for the alpha subunit of the NaV1.6 sodium channel, can lead to severe [...]

This was a retrospective study, gathering information on Dravet patients who, over the last nine years, had followed a strict ketogenic diet for at least 12 weeks. In total, there were 60 children identified. The duration of their ketogenic diets ranged from 12 weeks to 54 months, with a median duration of 44 weeks. [...]

Many of the drugs used to treat Dravet Syndrome work by interacting with GABAA receptors.  Each GABAA receptor is composed of subunits, and there are different versions of receptors depending on which subunits they have. Drugs have unwanted side-effects, and it is worth asking: if we hit just one specific kind of GABAA receptor, [...]
