This Australian disability knowledge guide explains Hunter Syndrome (MPS II), how it may affect daily living and what people should understand about the National Disability Insurance Scheme. Access to the NDIS is based on the person's individual circumstances and permanent impairment, not just the name of a condition.

Understanding Hunter Syndrome (MPS II)

Hunter syndrome (MPS II) is an inherited lysosomal storage disorder in which the body lacks adequate activity of an enzyme used to break down certain large sugar molecules. It can affect joints, hearing, the airway, heart and other organ systems, and some people also experience neurological and developmental changes.

Every person has different strengths, preferences and needs. A diagnosis can explain the cause of an impairment, but meaningful supports should be guided by what the person wants to achieve and what they need help doing day to day.

Recognising possible symptoms and impairments

Features that may be relevant include the following, although the mix and severity vary from person to person.

• Joint stiffness and skeletal changes influencing mobility
• Hearing difficulties or recurring ear issues
• Growth and physical access differences
• Possible developmental or cognitive changes in severe forms
• Airway and heart complications requiring clinical monitoring
• Different severity across individuals

How daily living and participation can be affected

A child might need accessible routines, support with communication or mobility, and assistance participating in community activities in addition to ongoing specialist healthcare.

The NDIS considers functional capacity in areas including communication, social interaction, learning, mobility, self-care and self-management. A useful description of needs considers what happens in the home and community, how often assistance is required and what the person can do with equipment or accessible information.

Practical person-centred approaches

• Use occupational therapy and physiotherapy advice to adapt daily tasks and access.
• Support communication using hearing-accessible methods when needed.
• Do not improvise treatment of respiratory, cardiac or other medical complications.
• Respect individual capacity for learning, choice and independence.

Effective support involves consent, safeguarding the person's rights, and working with their chosen family members or representatives. Changes in medical status should be referred to qualified clinicians rather than managed through assumptions.

Hunter Syndrome (MPS II) and NDIS eligibility

Hunter syndrome, also known as mucopolysaccharidosis type II, is expressly included in the NDIS List B mucopolysaccharidoses group. Different forms and impairments require person-specific assessment.

Generally, the NDIS requires applicants to meet age and residence rules, and either disability or early intervention criteria. Disability criteria concern impairments that are or are likely to be permanent, substantially reduce functional capacity, affect social or economic participation, and are likely to require NDIS supports throughout life. Early intervention requirements are different and may be relevant for some children and adults.

The NDIA's historical List A and List B guidance indicates conditions likely to satisfy particular elements of the requirements. List A concerns conditions likely to meet the disability requirements, while List B concerns conditions likely to involve permanent impairment. See the current NDIS eligibility guidance for the applicable rules. A listed condition is not an automatic promise of a funded plan.

What evidence is useful when applying?

The NDIA needs to understand functional impacts and any relevant ongoing impairments. Examples of useful evidence, depending on the person, include:

1. A diagnosis and any qualifying subtype from an appropriately qualified specialist.
2. Information about impairment permanence, health treatments considered and remaining functional limitations.
3. Occupational therapy, speech pathology, physiotherapy or other relevant functional assessments.
4. Examples of where disability-specific equipment, supervision, prompting or hands-on help is needed.
5. Evidence about work, study, relationships, social participation and expected long-term disability support needs.

If the person's condition changes over time, explain both their current needs and periods of increased difficulty. Describe real tasks and situations rather than relying only on general phrases such as 'requires assistance'.

NDIS supports that might be appropriate

Where someone is an eligible participant and the supports match their plan, disability funding might assist with daily living tasks, community participation, assistive technology, mobility or communication needs, disability-related allied health and support coordination. Specific supports are not guaranteed. Funding must be used for approved purposes and comply with the current NDIS support rules.

Medical diagnosis, prescribed medicines, disease-specific therapies, operations, hospital care and routine health treatment are primarily healthcare responsibilities. The NDIS can fund certain disability-related health supports in defined situations, but staff must have appropriate instructions, authorisation and competency for complex tasks.

Support from Beyond Health Services

Our team welcomes conversations about a participant's daily routines, goals, communication preferences, personal care requirements and participation in community life. Depending on the individual's circumstances, we can discuss support workers, relevant therapy services, disability-related nursing, support coordination and other suitable disability supports. Before services are arranged we work through the referral process and discuss relevant plan funding and staff requirements.
