Author Information
Author(s): Maranda Bruno, Lemieux Nicole, Lemyre Emmanuelle
Primary Institution: CHU Ste-Justine, Université de Montréal
Hypothesis
How does deletion 18p affect cognitive outcomes in a family?
Conclusion
Cognitive performance may be more variable than previously suggested within the same family, and verbal abilities could be superior to non-verbal abilities in some individuals.
Supporting Evidence
- The proband and her sister both exhibit short stature and dysmorphic features.
- The mother has a global IQ of 43, indicating moderate mental retardation.
- Cognitive performance varies significantly among family members with the same chromosomal deletion.
Takeaway
This study looks at a family where a genetic condition called deletion 18p was passed from mother to daughters, showing that their thinking skills can be very different from each other.
Methodology
Chromosome analysis and psychological evaluations were performed on the family members.
Potential Biases
Potential bias in cognitive assessments due to small sample size and subjective evaluations.
Limitations
The study is based on a small family sample, which may not represent the broader population.
Participant Demographics
The family consists of a mother and her two daughters, all affected by deletion 18p.
