Definition
Autosomal dominant neurodegenerative disease. Leads to problems with movement, emotion, and cognition.
Clinical features include: - Jerky, involuntary movements - Speech or swallowing difficulties - Slowed thinking - Irritibility, mania, OCD, anxiety, depression
Pre-symptomatic testing is available.
The disease is due to an unstable CAG repeat, which can expand in successive generations causing anticipation. |

Definition
Autosomal recessive. A disease caused by excessive absorption of iron. Symptoms begin 40-60 (after menopause in women).
Clinical features include: - Hepatomegaly (large liver) - Cirrhosis of the liver - Diabetes - Arrhythmia - Arthritis - Skin pigmentation
Later stages can cause liver disease and heart failure. It can be treated by bleeding.
Carrier frequency in Caucasians 1/9 but penetrance varies. |

Definition
To be considered early onset, under age 65. Autosomal dominant. Makes up to 3-10% of Alzheimers.
Clinical features include: - Confusion - Memory loss, language deficits - Agitation, withdrawal - Hallucinations - Seizures - Increased muscle tone
Brain findings show increased B-amyloid plaque formation and intraneuronal neruofibrillary tangles.
There are gene panels, molecular testing, and predictive testing. |

Definition
Most common type of muscular dystrophy in adults. Autosomal dominant trinucleotide repeat disorder (has premutations and mutations, more common to inherit through mother).
Clinical features: - Myotonia is sustained muscle contraction, so inability to loosen grasp - Cataracts - Fatigue, pain - Cardiac complications - Lower IQ - Hypersomnia - Anxiety, depression - Inverted V -shaped upper lip, droopy eyelids
Prenatal and molecular testing available. |

MELAS stands for Mitochondrial encephalomyopathy, lactic acidosis, and seizure-like episodes. Mitochondrial inborn error of metabolism.
Clinical features include: - Seizures - Recurrent headaches - Stroke-like episodes (can lead to loss of motor skills or intellectual disability) - Lactic acidosis - Abdominal pain, vomiting - Exercise intolerance, muscle weakness - Difficulty breathing - RAGGED RED FIBERS
Mutation in mitochondrial DNA, disrupts respiratory chain. Therefore, mitochondrial inheritance.
Variety due to HETEROPLASMY |

Young Onset Parkinson's Disease |
|
Definition
If Parkinson's disease occurs before 50 it is considered young onset. In this case it is less likely to be multifactorially inherited and more likely to be due to a causative gene. These causative genes are numerous and can have any mode of inheritance.
Clinical features include: - Motor symptoms like tremors, muscle rigidity, slow movement, involuntary movement - Cognitive features like mood disorders, problems focusing, or hallucinations - Other symptoms like pain, loss of sense of smell, or urinary urgency - People with young onset Parkinsons will generally have more involuntary movement and fewer cognitive symptoms
Can be treated with replacement dopamine medication and therapies. Direct to consumer tests are available. |

Definition
Stands for mitochondrial neurogastrointestinal encephalopathy.
Clinical features include: - Gastrointestinal issues (pain, vomiting) - Neuropathy (numbness, pain in extremities) - Hearing loss - Leukoencephalopathy (white brain matter disease) - Droopy eyelids
Even though this is a mitochondrial disease it is AUTOSOMAL RECESSIVE. It is caused by not being able to break down thymidine, which builds up and hurts mitochondria.
To test for it, you can test for Thymidine Phosporylase Enzyme Activity or the level of thymidine. |

Definition
Stands for Cerebral Autosomal Dominant Arteriopathy Subcortical Infaracts Leukoencephalopathy.
Clinical features include: - Recurrent strokes - Cognitive impairment - Migraine with aura - Psychiatric disturbances
Gene mutation causes smooth muscle cells on the walls of the arteries to break down. Progressive damage to blood vessels in the brain causes stroke and other symptoms.
Autosomal dominant, varies greatly. Genetic testing available. |
