Summary
Aarskog syndrome presents significant clinical variability and age-related phenotype changes in males. Adult diagnosis is challenging due to the regression of most prepubertal signs.
Area of Science:
- Genetics
- Pediatrics
- Clinical Medicine
Background:
- Aarskog syndrome is a rare genetic disorder affecting males.
- Clinical presentation exhibits significant variability.
- Phenotypic expression changes with age, complicating diagnosis.
Purpose of the Study:
- To detail the Leuven experience with 52 males diagnosed with Aarskog syndrome.
- To characterize clinical variability, age-related phenotype changes, and identify new signs.
- To assess the long-term social integration and functioning of affected adults.
Main Methods:
- Retrospective review of clinical data from 52 males with Aarskog syndrome.
- Analysis of phenotypic features across different age groups.
- Evaluation of cognitive function, behavioral symptoms, and adult outcomes.
Main Results:
- Mental retardation observed in at least 30% of cases, often mild.
- Hyperactivity and attention deficit symptoms were common but resolved by adolescence.
- Adults showed satisfactory social integration with minimal residual prepubertal signs.
Conclusions:
- Aarskog syndrome displays considerable clinical heterogeneity and evolving phenotype.
- Behavioral symptoms are transient, resolving by late adolescence.
- Adult diagnosis is difficult due to the near-complete resolution of characteristic prepubertal features.
