We are accepting new referrals. New patients will need a referral to be seen. Infants referred for an abnormal newborn screen will be seen promptly.

Visit type:
- New patient consult, transfer of care, second opinion or return visit/ongoing care
ALL relevant clinical documents
- Clinic notes
- Genetic test results
- Information about family history and family members relevant to the disorder (including family members’ relevant genetic tests if available)
- Medication history
- Growth charts/curves
- Biochemical screening and lab reports*
- Imaging and diagnostic reports (images can be uploaded to PowerShare)
- Previous specialty evaluations
Patient’s full name, DOB, sex, address, guardian contact information and insurance
Referring provider’s name, phone, fax and the referral coordinator’s email address so that we may contact you if additional information is needed

Please note:

Newborn screens: When referring a newborn for an abnormal newborn screening report, please include the screening report(s).
- For questions about a newborn screening report, please contact the Newborn Screen Lab at the Washington State Department of Health (DOH) at 206-418-5410.
- DOH also offers excellent provider resources, including a Healthcare Provider Manual (see page 11 of the manual for information on how abnormal results are handled).
- You may also call Seattle Children’s Provider-to-Provider Line at 206-987-7777 and ask to speak with the biochemical genetics doctor on call.
MTHFR: We do not accept referrals for the common polymorphisms, but we do see patients with homocystinuria due to MTHFR mutations. For more information, see MTHFR: ACMG Practice Guideline: Lack of Evidence for MTHFR Polymorphism Testing (Genetics in Medicine).
Mitochondrial disease: We see patients through age 20. Please refer patients 21 and older to the Biochemical Genetics Clinic at the University of Washington, 206-598-1800.
Autism and developmental delays: Patients with isolated autism or developmental delays who require a genetics workup should be referred to Medical Genetics. Medical Genetics will refer back to us if appropriate.
Wilson disease: These patients are seen by Dr. Sihoun Hahn, and initial visits are 60 to 90 minutes. There are specific referral requirements for Wilson disease. Please submit the following with your referral:

- 24-hour urine copper
- CBC with differential
- Lipid panel
- Serum copper
- Ceruloplasmin
- Liver function labs:
  - APTT
  - PT INR
  - AST
  - ALT
  - Alkaline phosphatase
  - Albumin
  - Total protein
  - Alpha-fetoprotein
  - Bilirubin (conjugated and unconjugated)
  - Gamma glutamyltransferase
- If you have a report from a liver biopsy and/or notes from a hepatology or psychiatric evaluation, abdominal ultrasound, complete liver elastography or slit lamp eye exam looking for Kayser-Fleischer rings, those would also be helpful to send with the referral.
Congenital disorders of glycosylation (CDG): If you are considering referring for CDG, please call our Provider-to-Provider Line and ask to speak with someone on our team. It’s a more complicated referral, and we want to give you support. These patients are seen by Dr. Lam, and initial visits are 90 minutes.
Do not send your patient’s whole chart; please send only notes and documentation specifically relevant to the disorder.
