Overview - Fragile X Syndrome

Description of Fragile X Syndrome

Fragile X syndrome is a genetic disorder characterized by a series of physical, mental and emotional symptoms that include a number social deficits such as a reduced ability to process information and learn.

Disease Classification

Condition: Fragile X Syndrome
Disease Family: Genetic Disorder
Organ System: Nervous System
ICD-10 Chapter: Congenital Malformations, Deformations and Chromosomal Abnormalities
ICD-10 Code: Q99.2

Fragile X Syndrome Symptoms:

Physical symptoms (e.g. large ears, large testes, elongated face, poor muscle tone), cognitive impairment (e.g. autism-like behavior, learning disability)

Also known as:

Fragile X chromosome

Drug Interactions

THC Interaction with Pharmaceutical Drugs

  • THC can enhance the effects of drugs that cause sedation and depress the central nervous system, such as benzodiazepines, barbiturates, and alcohol, for example. 
  • THC is metabolized by and an inhibitor of a number of enzymatic liver pathways referred to as cytochrome P450. There are more than 50 enzymes belonging to this enzyme family, a number of which are responsible for the breakdown of common drugs such as antidepressants (e.g. amitriptyline, doxepine, fluvoxamine), antipsychotics (haloperidol, clozapine, stelazine), or beta-blockers (propranolol, theophylline, warfarin).  Thus patients taking these classes of medication may find that THC increases the concentration and effects of these drugs as well as the duration of their effects.
  • Clinical observation suggests no likely interactions with other pharmaceuticals at a total daily dose of up to 20mg THC.

CBD Interaction with Pharmaceutical Drugs

  • CBD may alter action on metabolic enzymes (certain drug-transport mechanisms), and as such may alter interactions with other drugs, some of which may produce therapeutic or adverse effects. For instance, CBD interacts with the enzyme cytochrome P450 3A4 and cytochrome P450 2C19, increasing the bioavailability of anti-epileptic drugs such as clobazam (a benzodiazepine). This makes it possible to achieve the same results at significantly lower dosages, reducing treatment costs and risks of adverse effects. 
  • Groups of drugs affected include: anti-epileptic drugs, psychiatric drugs, and drugs affecting metabolic enzymes, for example.
  • Clinical observations suggest no likely interactions with other pharmaceuticals at a total daily dose of up to 100mg CBD

Dosing Considerations

THC Dosage Considerations

  • THC micro dose:  0.1 mg to 0.4 mg (0.001mg/kg to 0.005mg/kg)
  • THC low dose:  0.5 mg to 5 mg (0.006mg/kg to 0.06mg/kg)
  • THC medium dose:  6 mg to 20 mg (0.08mg/kg to 0.27mg/kg)
  • THC high dose:  21 mg to 50+ mg (0.28mg/kg to 0.67mg/kg)
Formula for converting a set dose into mg/kg considerations: mg ÷ kg = mg/kg
(sample conversion calculated on a person weighing 75kg)

CBD Dosage Considerations

  • CBD low dose:  0.4 mg to 19 mg (0.005mg/kg to 0.25mg/kg)
  • CBD medium dose: 20 mg to 99 mg (0.26mg/kg to 1.32mg/kg)
  • CBD high dose:  100 mg to 800+ mg (1.33mg/kg to 10.7mg/kg)
  • (upper limits tested ~1,500mg)
Formula for converting a set dose into mg/kg considerations: mg ÷ kg = mg/kg
(sample conversion calculated on a person weighing 75kg)
