Did you know?

To biochemically diagnose many neurotransmitter disorders, neurotransmitter and metabolite levels must be obtained by extracting cerebral spinal fluid (CSF). In such cases, molecular testing may help avoid a lumbar puncture and the associated risks for the patient.

About neurotransmitter disorders

  • The inborn errors of neurotransmission are a genetically heterogeneous set of conditions affecting the metabolism and transport of neurotransmitters.

  • Treatments and clinical trials are available for some of these disorders so early diagnosis may help improve long term outcomes.

  • These disorders typically present in infancy or childhood, but later onset presentations have also been described.

  • Features can include developmental problems, hypotonia, early onset parkinsonism, dystonia, ataxia, autonomic dysfunction, oculogyric crises, behavior abnormalities, psychiatric disturbances, epilepsy, increased startle response, sleep disturbances, SIDS, and SUDEP (sudden unexplained death in epilepsy), and vary depending on the underlying disorder. In some disorders, diurnal fluctuation of symptoms may also be present.

Program eligibility

This program is available to patients in the US who are suspected of having, or have clinical symptoms consistent with, a neurotransmitter disorder.

Genetic testing with Invitae

The PTC Pinpoint program offers testing with the Invitae Neurotransmitter Disorders Panel.

The Invitae Neurotransmitter Disorders Panel analyzes up to 37 genes that are associated with disorders of monoamine metabolism, GABA metabolism, and neurotransmitter receptors and transporters.

Genetic counseling

Individuals tested through the PTC Pinpoint program are eligible for post-test genetic counseling to help them understand their test results. This service is provided through GeneMatters, a third-party genetic counseling service, and is made available by Invitae at no charge as part of the program.

Patients can access genetic counseling by having their provider:

1. Complete the referral form
2. Attach the genetic test results to the referral form
3. Fax both the referral form and the genetic test results to GeneMatters at 612-808-5186

Patients will then be contacted by GeneMatters to schedule an appointment.

Family follow-up testing

Invitae offers family variant testing for all blood relatives of patients who undergo testing at Invitae and are found to have a pathogenic or likely pathogenic variant. Our family variant testing reports on the variant(s) that was identified in the original family member, as well as any other pathogenic variant(s) found in the full gene.

If your patient tests positive through the PTC Pinpoint program, all of his or her blood relatives are eligible for family variant testing.
