Familial Migraine and Epilepsy (CACNA1A) Targeted Testing

Familial Migraine and Epilepsy (CACNA1A) Targeted Testing

Short Name:
CACNA1A Targeted
Targeted Testing Price:
$225
Targeted Testing CPT:
81403
Gene Name(s):
Disorder Name(s):
OMIM:
601011
General Information:

Pathogenic variants in the CACNA1A gene cause episodic ataxia type 2, familial hemiplegic migraine 1, and spinocerebellar ataxia 6. A single pathogenic variant in one copy of the CACNA1A gene has been reported previously in patients with different migraine phenotypes as well as in patients with episodic ataxia and epilepsy. Recently, the c.3043G>A (p.Glu1015Lys) variant was identified in Indiana Amish patients with isolated epilepsy and migraine. This targeted test will specifically analyze the c.3043G>A variant.

  • Specimen Requirements

    Label specimens with the patient’s full name, date of birth, collection date and source (if appropriate). Please use the tube size appropriate for the sample volume.

    Peripheral Blood

    • Infants: Minimum of 2-3 ml of whole blood in a purple top (EDTA) tube.
    • Adults and children over 2 years of age: Minimum of 3-5 ml of whole blood in a purple top (EDTA) tube.


    Cord Blood

    • Minimum of 3-5 ml of whole blood in a purple top (EDTA) tube.


    Isolated DNA

    • Minimum of 50 µl at a concentration of 100 ng/µl. Please include concentration on the specimen label.
  • Storage and Shipping Information

    Blood samples are stable at room temperature (15ºC to 25ºC) for one day or at 2º to 8ºC for up to 5 days. Blood samples should not be frozen at any time.

    DNA sample stability is dependent on the methodology used for the isolation. In general the DNA should be stable and can be shipped ambient or cold, following the directions below.

    Specimens from outside facilities should be packaged according to standard medical safety practices. Refrigerate samples if stored overnight prior to shipping. In hot weather, include a cool pack in the shipping container. Do not allow the specimen to freeze at any time. Package the completed test requisition inside the packaging container with the specimen. Please ship by overnight priority.

    Specimens should not be shipped on Fridays, Saturdays or the day preceding a holiday.

    **Holiday schedules will be noted on our website at least one week prior to the holiday. Feel free to contact us with any questions.
