Patients diagnosed with PBD
Collection of medical records and images (retrospective and prospective), Next-generation panel, Drug screening, and Consultation
Genetic: Next-generation panel
Molecular testing will be offered to participants whose mutations have not been found. Molecular testing will be done with a next-generation panel of 75 genes on a research basis. Genetic counselling services are available to participants.
Other: Consultation in Ophthalmology
Participants seen in consultation will have an OCT (optical coherence tomography) eye exam and FAF (fundus autofluorescence) photography.
- Documentation of the clinical findings [ Time Frame: Yearly up to 10 years ]Clinical findings include but are not limited to: life span, growth parameters, development, vision, hearing, neurological examinations, renal problems, adrenal function, skeletal problems, and any other system involvement.
- Peroxisome function testing [ Time Frame: Yearly up to 10 years ]To include very long chain saturated, branched and polyunsaturated fatty acids, bile acids, plasmalogens, pipecolic acid, adrenal functions, liver functions, and urine oxalate.
- Identification of PEX gene mutations [ Time Frame: Once ]Through next-generation panel
- Development of leukodystrophy [ Time Frame: Yearly up to 10 years ]Identification of patterns and course by MRI
- Scoring of fundus photography (OCT and FAF) [ Time Frame: Yearly up to 10 years ]Identification of patterns and course
- Genotype-phenotype correlation [ Time Frame: Yearly up to 10 years ]Correlation of mutation type to peroxisome biochemistry, number and type of disease complications.
- Frequency of various disease complications in the PBD population [ Time Frame: Yearly up to 10 years ]Neurological, vision, hearing, liver dysfunction, adrenal insufficiency, osteopenia, renal stones
Biospecimen Retention: Samples With DNA
