Transmission is autosomal recessive. Genetic counseling should be offered to at-risk couples (both individuals are carriers of a disease-causing mutation) informing them that there is a 25% risk of having an affected child at each pregnancy.

Also asked, Is Refsum disease dominant or recessive?

Refsum disease is an autosomal recessive genetic disorder.

Also, How common is Refsum disease?. About 60 cases of Refsum disease (RD) have been reported worldwide. Prevalence rates are not known but the disorder may be underdiagnosed. Prevalence has been estimated to be 1/1,000,000 in the United Kingdom. Males and females are affected equally.

Furthermore, Is there a cure for Refsum disease?

Although there is no cure, phytanate levels in Refsum disease patients can be reduced by plasmapheresis and a strict diet. Pharmacological up-regulation of the omega-oxidation of phytanic acid may form the basis of the new treatment strategy for adult Refsum disease in the near future.

What is the defect in Refsum disease?

Refsum disease is a recessive disorder characterized by defective peroxisomal alpha-oxidation of phytanic acid. [4,5,6] Consequently, this unusual, exogenous C20-branched-chain (3,7,11,15-tetramethylhexadecanoic acid) fatty acid accumulates in blood and tissues.

What is Gaucher disease?

Gaucher disease is a rare genetic disorder passed down from parents to children (inherited). When you have Gaucher disease, you are missing an enzyme that breaks down fatty substances called lipids. Lipids start to build up in certain organs such as your spleen and liver.

What is Bassen Kornzweig syndrome?

Bassen-Kornzweig syndrome is caused by a defect in a gene that tells the body to create lipoproteins (molecules of fat combined with protein). The defect makes it hard for the body to properly digest fat and essential vitamins.

What gene causes Usher syndrome?

Usher syndrome type III is most often caused by mutations in the CLRN1 gene. The genes associated with Usher syndrome provide instructions for making proteins involved in normal hearing, balance, and vision.

What are peroxisomal disorders?

Peroxisomal disorders are a heterogeneous group of inborn errors of metabolism that result in impairment of peroxisome function. In most cases, this results in neurologic dysfunction of varying extent.

What is infantile Refsum disease?

Definition. Infantile Refsum disease (IRD) is a medical condition within the Zellweger spectrum of perixisome biogenesis disorders (PBDs), inherited genetic disorders that damage the white matter of the brain and affect motor movements.

Can Fabry disease be cured?

There is no cure for Fabry disease. Recombinant alpha-galactosidase A (alpha-Gal A), the enzyme that is deficient in patients with Fabry disease, and migalastat hydrochloride, an oral pharmacologic chaperone that facilitates trafficking of alpha-Gal A to lysosomes, are therapeutic options for eligible individuals.
