How Do You Spell REFSUM DISEASE?

Pronunciation: [ɹɪfsˈʌm dɪzˈiːz] (IPA)

Refsum disease is a rare genetic disorder that affects the nervous and muscular systems. The word "Refsum" is spelled with the IPA phonetic transcription as [ˈrɛfsʊm]. The 'r' sound is pronounced with the tip of the tongue curled backward, followed by a short 'ɛ' vowel sound. The 'f' sound in the second syllable is pronounced as a voiceless bilabial fricative, followed by a short 'sʊ' sound. This spelling and phonetic pronunciation are essential in distinguishing the disease from other similar-sounding conditions.

REFSUM DISEASE Meaning and Definition

1. Refsum disease, also known as heredopathia atactica polyneuritiformis, is a rare inherited disorder characterized by the accumulation of high levels of phytanic acid in the body. This condition is caused by a deficiency of an enzyme called phytanoyl-CoA hydroxylase (PAHX), which is responsible for the breakdown of phytanic acid in the body. As a result, phytanic acid builds up to toxic levels in various tissues, including the blood and nervous system.

   The excessive accumulation of phytanic acid leads to a wide range of symptoms, such as progressive vision loss, muscle weakness and wasting, hearing loss, poor balance and coordination, loss of smell, and peripheral neuropathy. Other neurological features may include impaired cognition, ataxia, and peripheral neuropathy. Furthermore, individuals with Refsum disease may exhibit distinctive physical features such as retinitis pigmentosa, facial abnormalities, and skeletal abnormalities.

   Diagnosis of Refsum disease is typically based on clinical evaluation, including a detailed medical history, physical examination, and biochemical testing. Genetic testing may also be used to confirm the diagnosis by identifying mutations in the PAHX gene. Treatment options for Refsum disease mainly involve dietary management, aiming to reduce the levels of phytanic acid through a low-phytanic acid diet. Removing or limiting dietary sources of phytanic acid, such as certain types of meat, dairy products, and fish, and using oral medications like glycerol trioleate may help manage the symptoms and slow down the progression of the disease.
