12 Questions
What could happen if the genetic diagnosis is not made or delayed?
The developing brain may lose the 'window of opportunity' for explicit support.
Why is it important to focus on the neurocognitive underpinnings of behavior?
Behavioral problems may arise from different information processing deficits.
What technological advancement has improved the detection of genetic variations in unborn children?
Screening maternal blood
What does the text suggest about early screening for neurobehavioral problems in young children with SCT?
It can help identify targets for early, tailored support and intervention programs.
What does the text imply about the development of neurocognitive mechanisms in early childhood?
Precursors of some mechanisms can already be measured in early childhood.
Why is knowledge about the development of children with SCT important?
To provide appropriate support as early as possible when needed.
What is the estimated prevalence of sex chromosome trisomies (SCT) in live births?
1 in 650 to 1 in 1000
Why are individuals with SCT often underdiagnosed?
Symptoms are treated without knowledge of the underlying genetic condition
What genetic variations can lead to Klinefelter syndrome and XYY syndrome?
Sex chromosome trisomies involving the X or Y chromosomes
Why may up to 75% of individuals with SCT never be diagnosed?
Because symptoms are often treated without knowing the genetic condition
What is the cause of chromosome trisomies like sex chromosome trisomies (SCT)?
Spontaneous error during early cell division
What is one reason for the underdiagnosis of individuals with SCT?
Treatment of symptoms without knowledge of the genetic condition
This quiz covers the topic of chromosomal conditions in humans, focusing on Specific Chromosome Trisomies (SCT). Learn about common genetic variations such as the 47,XXY karyotype in males and the 47,XXX karyotype in females, and the reasons why SCT are often underdiagnosed.
