In one aspect, the present invention features a method of inhibiting proliferation and/or reducing survival of a cell comprising a GNAQ polynucleotide or polypeptide having a R183Q or Q209L mutation, comprising contacting the cell with puromycin or a puromycin analog, thereby inhibiting proliferation and/or reducing survival of the cell. In another aspect, a method of treating a vascular malformation or related condition in a subject, comprising administering to the subject an effective amount of puromycin or a puromycin analog is featured. In another aspect, the present invention features a method of identifying a candidate agent that modulates a GNAQ R183Q or Q209L mutation-associated disease, comprising contacting a cell comprising a GNAQ polynucleotide or polypeptide having a R183Q or Q209L mutation with puromycin and a candidate agent and comparing viability of the contacted cell with a reference level of viability, wherein an alteration in viability indicates that the candidate agent modulates the GNAQ R183Q or Q209L mutation-associated disease.

Compositions and methods for treating vascular malformation and related conditions

The present invention relates to the use of cannabidiol (CBD) in the treatment of Sturge Weber syndrome. CBD appears particularly effective in reducing all types of seizures and non-seizure symptoms in patients suffering with Sturge Weber syndrome. Preferably the CBD used is in the form of a highly purified extract ofsuch that the CBD is present at greater than 98% of the total extract (w/w) and the other components of the extract are characterised. In particular the cannabinoid tetrahydrocannabinol (THC) has been substantially removed, to a level of not more than 0.15% (w/w) and the propyl analogue of CBD, cannabidivarin, (CBDV) is present in amounts of up to 1%. Alternatively, the CBD may be a synthetically produced CBD.

Use of cannabinoids in the treatment of epilepsy

The present invention relates to the fields of neurological and skin disorders. More specifically, the present invention provides methods and compositions for diagnosing and prognosing Sturge-Weber Syndrome (SWS), Klippel-Trenaunay-Weber Syndrome (KTWS), and Port Wine Stains (PWS). In one embodiment, a method for prognosing or monitoring treatment of a patient with SWS, KTWS and/or PWS comprises the steps of (a) providing a sample from the patient undergoing treatment; (b) determining the number of alleles in the sample comprising at least one activating somatic mutation in the guanine nucleotide-binding protein G subunit alpha (GNAQ) gene or protein; (c) comparing the number of alleles comprising the at least one somatic mutation to the number of alleles comprising the somatic mutation from a patient sample provided prior to undergoing treatment; and (d) determining that the patient is improving if there is a decrease in the number of alleles comprising the at least one somatic mutation from the sample of step (a).
