Genetic Services of WA

Genetic Services of WA (GSWA) provides a comprehensive statewide diagnostic and confidential counselling service in clinical genetics.

GSWA consists of 3 subspecialty sections:

  • Genetic Paediatric Services
  • Familial Cancer Program
  • Obstetrics and General Genetic Services.

Clients are primarily referred to GSWA by GPs, specialists, or hospital inpatient/outpatient wards or departments. Self-referrals may be accepted in some instances.

GSWA offers a full range of programs relevant to the modern practice of medical genetics. Services are provided by clinical geneticists and genetic counsellors working closely with molecular and cytogenetic laboratories and associated disciplines, such as diagnostic imaging and obstetrics.

The protocols and procedures accord with the Human Genetic Society of Australasia (external site) Guidelines for Genetic Service.

Indications for referral

Genetic Paediatric Services

  • A child with features suggestive of a specific genetic disorder.
  • Unexplained congenital abnormalities or childhood disabilities affecting intellectual development, hearing or vision. Please note that there are strict criteria around referrals for hearing – clinicians are advised to read the referral guidelines.
  • A child with a known family history of a genetic disorder who needs assessment
  • Counselling for families/carers following a genetic diagnosis in a child regarding adjustment and coping; talking with children/family/friends/school; pregnancy planning and decision-making.

Familial Cancer Program

  • Familial clustering of a specific cancer, for example bowel or breast, particularly with 2 or more affected first degree relatives with a young age of onset (less than 50 for colorectal or ovarian, less than 40 for breast cancer).
  • Relatives with more than 1 separate primary cancer.
  • Family history of a known pathogenic cancer causing gene change.

Obstetrics and General Genetic Services

  • A family history of a specific genetic disorder, particularly when considering pregnancy.
  • An adult with features suggestive of a specific genetic disorder.
  • Fetal anomaly diagnosis and counselling.

Specialist rooms, GP’s and WACHS

All Specialist Rooms, GP’s and WACHS referrers are being advised to direct all referrals for genetic outpatient services to the WA Health Central Referral Service (CRS). Referrals that are faxed or emailed directly to GSWA after 1 July 2020 will not be actioned.

Familial Cancer Program referrals:

Complete a Familial Cancer Program referral form (PDF 319 KB) and fax it with any relevant investigations to the CRS on 1300 365 056.

General Genetics, Obstetric or Paediatric referrals:

Referrers will need to complete one of the standardised referral forms and send it to the CRS via:

  • Fax: 1300 365 056
  • Healthlink Secure Messaging: crefserv
  • Postal address: 
    PO Box 3462
    Midland WA 6056

If your referral is regarding a pregnancy you must clearly indicate this on the CRS referral form for expedited triage. GSWA will generally see a pregnant patient within one week of receiving the referral from CRS.

Referrals from other WA Health services (Metro)

A referral letter or consult request should be sent to GSWA specifying the reason for referral and referring doctor’s name and address.

Include the following patient information:

  • full name (including maiden name if relevant)
  • current address and contact details
  • date of birth
  • relevant personal or family history
  • ·other medical information that may be relevant
  • copies of relevant test results.

If you are considering a referral, please read the referral guidelines for clinicians.

Please ensure that the client is informed of the referral to GSWA. Once the referral has been received, a genetic counsellor will contact the client by letter or telephone.

GSWA consent forms can also be filled out prior to the client’s appointment:
