How is Rippling Muscle Disease usually inherited?
- A.
Autosomal dominant
- B.
Autosomal recessive
- C.
X-linked recessive
- D.
Mitochondrial inheritance
Correct Answer
A. Autosomal dominantExplanation
Rippling Muscle Disease is usually inherited in an autosomal dominant manner. This means that a person only needs to inherit one copy of the mutated gene from either parent to develop the disease. The mutated gene is located on one of the autosomes (non-sex chromosomes) and can be passed down from generation to generation. Unlike autosomal recessive inheritance, where both copies of the gene need to be mutated, autosomal dominant inheritance allows for the disease to be passed on even if only one parent carries the mutated gene.Rate this question:

Rippling muscle disease can also cause features of other conditions known as:
- A.
Cachexia
- B.
Cardiomyopathies
- C.
Dysautonomia
- D.
Caveolinopathies
Correct Answer
D. CaveolinopathiesExplanation
Rippling muscle disease is a rare genetic disorder that primarily affects the muscles. It is characterized by rippling or wave-like movements that occur under the skin in response to muscle contractions. In addition to these muscle abnormalities, individuals with rippling muscle disease may also exhibit features of other conditions known as caveolinopathies. Caveolinopathies are a group of genetic disorders that affect the caveolin proteins, which play a role in the formation of caveolae, small invaginations in the cell membrane. These conditions can cause a variety of symptoms, including muscle weakness, cardiomyopathies (diseases of the heart muscle), dysautonomia (dysfunction of the autonomic nervous system), and other related problems.Rate this question:

- B.
Isolated hyperCKemia
- C.
CAV3-related distal myopathy
- D.
Duchenne muscular dystrophy
Correct Answer
D. Duchenne muscular dystropHyExplanation
Duchenne muscular dystrophy is not considered a caveolinopathy because it is caused by mutations in the dystrophin gene, not the caveolin gene. Caveolinopathies are a group of genetic disorders that result from mutations in the caveolin gene, specifically caveolin-3 in the case of CAV3-related distal myopathy. Limb-girdle muscular dystrophy 1C and isolated hyperCKemia are also considered caveolinopathies as they are caused by mutations in the caveolin gene.Rate this question:
