Summary
Two out of five males with 47,XYY syndrome had port-wine stains. This suggests a potential link between this genetic condition and vascular birthmarks, warranting further investigation.
Area of Science:
- Genetics
- Dermatology
- Pediatrics
Background:
- 47,XYY syndrome is a chromosomal condition affecting males.
- Port-wine stains are common vascular birthmarks with a low population incidence.
- Previous studies have not reported an association between 47,XYY and port-wine stains.
Purpose of the Study:
- To investigate dermatological features in males with 47,XYY syndrome.
- To explore a potential association between 47,XYY and port-wine stains.
Main Methods:
- Case series presentation of five males diagnosed with 47,XYY karyotype.
- Clinical observation and documentation of dermatological findings, specifically noting the presence of port-wine stains.
Main Results:
- Two of the five (40%) males with 47,XYY syndrome presented with port-wine stains.
- The observed incidence in this small cohort is significantly higher than the general population rate of 0.5%.
Conclusions:
- The findings suggest a possible association between 47,XYY syndrome and port-wine stains.
- Further research is needed to confirm this association and elucidate potential underlying mechanisms.
