Fragile X Syndrome

1.

How many males and females does fragile X syndrome infect?

A.

1 in 3200 males and 1 in 7000 to 9000 females
B.

1 in 3600 males and 1 in 4000 to 6000 females
C.

1 in 3500 males and 1 in 5000 to 8000 females

Correct Answer
B. 1 in 3600 males and 1 in 4000 to 6000 females

Explanation
Fragile X syndrome is a genetic disorder that affects both males and females, but it is more commonly seen in males. The given answer states that the syndrome infects 1 in 3600 males and 1 in 4000 to 6000 females. This means that the syndrome is slightly more prevalent in males compared to females.

What gender is fragile X sydrome more commin in, males or females?

A.

Males
B.

Females

Correct Answer
A. Males

Explanation
Fragile X syndrome is a genetic disorder caused by a mutation in the FMR1 gene on the X chromosome. Since males have only one X chromosome, if it is affected by the mutation, they are more likely to develop the syndrome. On the other hand, females have two X chromosomes, so even if one is affected, the other X chromosome can compensate for the mutation, resulting in milder symptoms or being unaffected. Therefore, fragile X syndrome is more common in males.

What physical features would you see in a person with fragile X syndrome?

A.

Small ears, round face, and small chin
B.

Enlarged ears, square face, and medium chin
C.

Enlarged ears, long face, and prominent chin

Correct Answer
C. Enlarged ears, long face, and prominent chin

Explanation
A person with fragile X syndrome may exhibit physical features such as enlarged ears, a long face, and a prominent chin. These characteristics are commonly associated with this genetic condition.

What are the symptoms of fragile X syndrome?

A.

Mental retardation, large body size, tendency to avoid contact, hyperactive behavior, large facial features.
B.

Mental retardation, small body size, stairs off into space, calm behavior, small facial features.
C.

Mental retardation, medium body size, pays attention, normal behavior, large facial features.

Correct Answer
A. Mental retardation, large body size, tendency to avoid contact, hyperactive behavior, large facial features.

Explanation
The correct answer is mental retardation, large body size, tendency to avoid contact, hyperactive behavior, large facial features. Fragile X syndrome is a genetic disorder that causes intellectual disability and developmental delays. Individuals with fragile X syndrome often have a larger body size and facial features, as well as difficulties with social interaction and hyperactive behavior. This combination of symptoms is characteristic of fragile X syndrome.

How can you tell if a baby has fragile X syndrome?

A.

Large feet
B.

Large ears
C.

Large head

Correct Answer
C. Large head

Explanation
Fragile X syndrome is a genetic disorder that causes intellectual and developmental disabilities. One of the physical characteristics commonly associated with this syndrome is a large head. This is due to abnormal brain development, which can result in an enlarged skull. Therefore, if a baby has a larger than average head size, it may be an indication of fragile X syndrome. However, it is important to note that a large head alone is not enough to diagnose the condition, and further medical evaluation and genetic testing are required for a definitive diagnosis.

What are all the behavior characteristics you would see in somebody who has fragile X syndrome?

A.

ADD, normal movement, responds to various touch, auditory or visual stimuli
B.

ADD, speech impairments, problems sitting still, autistic behaviors, and unusual responses to various touch, auditory or visual stimuli.
C.

ADD and speech impairments

Correct Answer
B. ADD, speech impairments, problems sitting still, autistic behaviors, and unusual responses to various touch, auditory or visual stimuli.

Explanation
The correct answer includes a comprehensive list of behavior characteristics commonly seen in individuals with fragile X syndrome. These characteristics include attention deficit disorder (ADD), speech impairments, difficulties with sitting still, autistic behaviors, and unusual responses to various touch, auditory, or visual stimuli. This answer provides a more complete and accurate description of the behavior characteristics associated with fragile X syndrome compared to the other options.

Who passes fragile X syndrome to their children, mothers or fathers?

A.

Fathers
B.

Mothers

Correct Answer
B. Mothers

Explanation
Fragile X syndrome is an inherited genetic disorder caused by a mutation in the FMR1 gene. This gene is located on the X chromosome. Since mothers have two X chromosomes, they can pass the mutated gene to their children. Fathers, on the other hand, pass their Y chromosome to their sons, which does not carry the FMR1 gene. Therefore, mothers are the ones who pass fragile X syndrome to their children.

What can help with fragile X syndrome?

A.

Learning in the classroom like a normal child.
B.

Special education and learn in the classroom normally without major help outside of the school.
C.

Special education, speech and language therapy, behavior therapy, and occupational therapy.

Correct Answer
C. Special education, speech and language therapy, behavior therapy, and occupational therapy.

Explanation
Special education, speech and language therapy, behavior therapy, and occupational therapy can help with fragile X syndrome. Fragile X syndrome is a genetic disorder that affects cognitive development and causes learning disabilities. Special education provides tailored instruction and support to help individuals with fragile X syndrome learn in the classroom like a normal child. Speech and language therapy can assist with communication difficulties often associated with the syndrome. Behavior therapy helps manage behavioral challenges and improve social skills. Occupational therapy focuses on developing fine motor skills and promoting independence in daily activities.
