Abstract:
Hair and skin pigmentation changes are described in males with Menkes disease from birth to 12 years of age and in 28 obligate carrier or at-risk females. Pili torti were observed in all affected males and in 43% of the females studied. The presence of pili torti may be considered a reliable diagnostic feature of the carrier state. Suggestions are given for evaluation of the hair in individuals in Menkes pedigrees.
Insights
Menkes disease, a genetic disorder, causes hair and skin changes. Pili torti, a specific hair abnormality, is a reliable indicator for identifying carriers of this condition.
Area of Science:
- Genetics
- Pediatrics
- Dermatology
Background:
- Menkes disease is a rare genetic disorder affecting copper metabolism.
- It primarily impacts males, leading to significant health issues.
- Identifying carriers is crucial for genetic counseling and management.
Observation:
- This study examined hair and skin pigmentation in males with Menkes disease (birth to 12 years).
- It also evaluated 28 obligate carrier or at-risk females.
- Specific hair abnormalities, pili torti, were noted.
Findings:
- All affected males exhibited pili torti.
- Pili torti were present in 43% of the studied females.
- Pili torti serve as a reliable diagnostic marker for the Menkes disease carrier state.
Implications:
- The presence of pili torti can aid in early identification of carriers.
- This facilitates timely genetic counseling for at-risk families.
- Recommendations are provided for hair evaluation in Menkes pedigrees.
