The Inborn Error of Metabolism (IEM) Program provides monthly financial assistance to approved grantees with protein metabolic disorders to assist with the purchasing of low protein foods.

Non-food items, such as medications and supplements, cannot be purchased with money provided under the Program.

Conditions that qualify under the Program include:
    • HMG-CoA Lyase Deficiency;
    • Homocystinuria, not Pyridoxine responsive (cystathionine β synthase deficiency);
    • Lysinic Protein Intolerance (LPI);
    • Maple Syrup Urine Disease (MSUD);
    • Ornithine Amino Transferase Deficiency (Hyperornithinaemia, gyrate atrophy of the retina);
    • Dihydropteridine Reductase (DHPR) Deficiency;
    • Hyperphenylalaninemia;
    • Phenylketonuria (PKU);
    • Tyrosinaemia: Type I (Hepatorenal tyrosinaemia, fumarylacetoacetate hydrolase deficiency), Type II and Type III;
    • 3-methylcrotonyl-CoA Carboxylase Deficiency;
    • Cobalamin Deficiencies: A, B, C and D;
    • Glutaric Aciduria Type I (Glutaryl CoA dehydrogenase deficiency);
    • Isovaleric Aciduria;
    • Methylmalonic Acidaemia;
    • Propionic Acidaemia;
    • Argininaemia (Arginase deficiency);
    • Argininosuccinicaciduria (ASA lyase deficiency);

    • Citrullinaemia (ASA synthase deficiency);
    • N-Acetylglutamate Synthase (NAGS);and
    • Ornithine Transcarbamylase Deficiency (OTC).
These conditions are managed by a diet consisting of special low-protein, high-fat foods and phenylalanine-free protein substitute formula. Strict compliance to the diet is necessary to maintain health.

Frequently Asked Questions (FAQs)

What should the monthly grant be used for?
The monthly grant is only to be used to purchase prescribed foods for approved metabolic conditions. Conditions that qualify under the Program are listed on this page.

Do I need to stay on my prescribed diet if I want to receive the grant?
Yes, people receiving the IEM grant are required to inform the Department if they stop their diet so payments can cease.  People may be liable to repay funds if they fail to advise the Department in a timely manner.

I have PKU, am I automatically approved to go onto the IEM Program once the metabolic specialist signs the application?
No, approval to join the IEM Program can only be given by the Department.  The metabolic specialist provides assurance that the applicant has an approved condition and requires a low protein diet.

I see a dietician on a regular basis, can they sign the IEM application form?
No, a metabolic specialist is required to sign the IEM application form.

When do I get the monthly grant?
The monthly grant is processed by the Department in the first full week of each month and is for that month. Please allow a few days for funds to reach your account.

I didn’t receive a payment, what do I do?
If you don’t receive a payment, please contact the Department. The payment may have ceased because of out of date contact details or bank account details. If you do not contact the Department of Health to provide up to date details within four months, you will be removed from the program. You will then have to submit a new application form to  re-join the program and no back payment will be applicable.

What happens if I have shared custody arrangements for my child who has IEM?
Grant payments can be shared between parents that share custody of a child with an IEM condition.  Please contact the Department for further information. The Department will send paperwork to each party to complete.

What happens if my child is now over 18 years of age, but I am still receiving the grant on their behalf?
If it is appropriate for the person with the IEM condition to start receiving the grant and they are 18 years or over, both they and the person currently receiving the grant need to complete and submit a Change of Details - Form C to the Department. The Department must be informed in writing that the parent no longer wishes to receive the grant. Failure to do this may result in an overpayment which will require repayment to the Department.
