Fabry's disease: heterozygote detection by hair root analysis

Area of Science:

• Biochemistry
• Genetics
• Dermatology

Background:

• Fabry's disease (angiokeratoma corporis diffusum) is a rare genetic disorder.
• Accurate diagnosis is crucial for effective management and genetic counseling.

Purpose of the Study:

• To present a novel, reliable method for diagnosing Fabry's disease.
• To evaluate the applicability of this method for identifying heterozygotes.

Main Methods:

• Development of a technique to analyze alpha-galactosidase activity and protein content in single hair root cells.
• Application of the method to obligatorily heterozygous sisters and their offspring.

Main Results:

• The developed technique allows for the determination of alpha-galactosidase activity in individual hair roots.
• The method proved to be easy and reliable, especially for identifying heterozygotes.

Conclusions:

• This hair root analysis method offers a practical approach for Fabry's disease diagnosis.
• The technique is particularly valuable for identifying heterozygous carriers of Fabry's disease.
