List of diseases covered by the panel

Lab method: NGS panel

NGS panel with CNV


TAT: 6-9 weeks

Specimen requirements: 2-4 ml of blood with anticoagulant EDTA

1 µg DNA in TE, AE or pure sterile water at 100-250 ng/µl
The A260/A280 ratio should be 1.8-2.0. DNA sample should be run on an agarose gel as a single band, showing no degradation, alongside with a quantitative DNA marker.

Deletion/duplication analysis

Genes: CRHR1, GRN, MAPT

Lab method: MLPA

TAT: 4-6 weeks

Specimen requirements: 2-4 ml of blood with anticoagulant EDTA

1 µg DNA in TE, AE or pure sterile water at 100-250 ng/µl
The A260/A280 ratio should be 1.8-2.0. DNA sample should be run on an agarose gel as a single band, showing no degradation, alongside with a quantitative DNA marker.

Indications for genetic testing:

1. Confirmation of clinical diagnosis
2. Determination of differential diagnosis
3. Testing of at-risk asymptomatic adults
4. Genetic counseling

Frontotemporal dementia (FTD) is a degenerative condition characterized by progressive neuronal loss in the temporal and frontal lobes of the brain. Clinical presentations may include behavioral changes, language disturbances, aphasia, extrapyramidal signs, rigidity, bradykinesia, supranuclear palsy, saccadic eye movement disorders, and mutism.

FTD usually occurs between ages 40 and 60 years, but may appear earlier or later. Most individuals diagnosed with the disorder have had an affected parent with the clinical symptoms of frontotemporal dementia. FTD is inherited in an autosomal dominant manner.
