General Information:

Cockayne syndrome is a rare autosomal recessive multisystem disorder characterized by growth failure, mental retardation, progressive neurological dysfunction, premature aging, and photosensitivity. Variants in the DNA repair gene ERCC6 are responsible for the majority of Cockayne syndrome cases reported. The c.1293_1320del and c.2709+1G>T variants in exons 5 and 14 of the ERCC6 gene are the most frequent pathogenic variants found in the Amish population. This targeted test will specifically analyze these two variants.

    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.
