MERRF


Alternate names

MERRF Is also known as fukuhara syndrome, myoclonus epilepsy associated with ragged-red fibres, merrf syndrome

Description

MERRF (Myoclonic Epilepsy with Ragged Red Fibers) syndrome is a mitochondrial encephalomyopathy characterized by myoclonic seizures.

Most common symptoms of MERRF

  • Intellectual disability

MELAS


Alternate names

MELAS Is also known as mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes, melas syndrome, mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes

Description

MELAS (Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke) syndrome is a rare progressive multisystemic disorder characterized by encephalomyopathy, lactic acidosis, and stroke-like episodes. Other features include endocrinopathy, heart disease, diabetes, hearing loss, and neurological and psychiatric manifestations.

Most common symptoms of MELAS

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Short stature
  • Hearing impairment

MITOCHONDRIAL NON-SYNDROMIC SENSORINEURAL DEAFNESS


Alternate names

MITOCHONDRIAL NON-SYNDROMIC SENSORINEURAL DEAFNESS Is also known as isolated mitochondrial neurosensory deafness, isolated mitochondrial sensorineural deafness, mitochondrial non-syndromic neurosensory deafness

Description

Mutations in mitochondrial DNA (mtDNA) have been found to be associated with nonsyndromic sensorineural hearing loss. Matrilineal relatives within and among families carrying certain pathogenic mitochondrial mutations exhibit a wide range of penetrance, severity, and age of onset of hearing loss, indicating that the mitochondrial mutations by themselves are not sufficient to produce a deafness phenotype. Modifier factors, such as nuclear and mitochondrial genes, or environmental factors, such as exposure to aminoglycosides, appear to modulate the phenotypic manifestations (summary by Tang et al., 2007).

Most common symptoms of MITOCHONDRIAL NON-SYNDROMIC SENSORINEURAL DEAFNESS

  • Hearing impairment
  • Sensorineural hearing impairment
  • Vertigo
  • Tinnitus
