Progressive Retina Atrophy is a dominant genetic disorder.

Lou Gehrigs disease
Inheritance pattern for most forms of SMA is autosomal recessive, meaning that both parents are carriers of the disorder, and the chance of having a child affected with the disorder is 25% with each pregnancy.
One example of a nervous system breakdown caused by an autosomal recessive allele is spinal muscular atrophy (SMA). SMA is a genetic disorder that leads to the loss of motor neurons in the spinal cord, resulting in muscle weakness and atrophy. It is caused by mutations in the SMN1 gene on chromosome 5.
Spinal muscular atrophy is an autosomal recessive disease. The severity of spinal muscular atrophy varies, and is the most common genetic cause of infant death.

Often, a disorder of the motor neurons results in progressive muscle atrophy (shrinking and wasting) of some, if not all, the muscles of the body. Muscle twitching (fasciculation) is common among these disorders
Atrophy is progressive weakening and size reduction of muscle tissue which is usually the result of disease or disuse.
No. Huntington's Disease is a pathological process affecting subcortical structures, not the cerebellar cortex. It does cause generalized atrophy of the cerebral cortex, over time, however. It is a genetic disorder, autosomal dominant in its transmission process, and occurring on chromosome number 4.
SMA = Spinal muscular atrophy. There are different types of SMA, all I believe are genetic and are autosomal recessive. They cause weakness and paralysis in the lower motor neurons.
Cerebral atrophy itself is not usually fatal, but it can lead to progressive decline in cognitive function and motor skills, depending on the extent and location of the brain damage. Underlying conditions that cause cerebral atrophy, such as neurodegenerative diseases or severe head injuries, can be life-threatening. Prompt medical evaluation and treatment are necessary to address any associated symptoms and complications.
