Is it advisable to do exercise when affected by Mainzer-Saldino syndrome? Which activities would you suggest and how intense should they be?

Yes, gentle and supervised exercise is generally recommended for individuals with Mainzer-Saldino syndrome to maintain joint mobility and muscle strength, provided it is tailored to the individual’s specific skeletal and renal limitations. Because Mainzer-Saldino syndrome is a rare ciliopathy affecting the kidneys, eyes, and bones, any physical activity plan must be cleared by your multidisciplinary care team to ensure safety and prevent overexertion.

Is exercise safe for those with Mainzer-Saldino syndrome?

For patients living with Mainzer-Saldino syndrome, exercise is not contraindicated, but it must be approached with caution. The condition often involves cone-rod dystrophy and skeletal abnormalities like phalangeal cone-shaped epiphyses, which can affect balance and joint health. Exercise helps combat muscle atrophy and improves cardiovascular health, but high-impact activities that stress the joints or increase the risk of injury should be avoided.

What types of activities are recommended?

Focus on low-impact, sustainable movements that prioritize joint health. Recommended activities include:

• Swimming or water aerobics: Water provides buoyancy, reducing stress on the skeletal system.


• Modified Yoga or Tai Chi: Excellent for improving flexibility and balance without extreme weight-bearing.


• Walking: Use supportive, orthotic-friendly footwear to manage potential foot skeletal issues.


• Supervised Resistance Training: Light, low-repetition strength training can help protect joints by building supportive muscle tissue.

How should one begin an exercise program?

Starting an exercise program for Mainzer-Saldino syndrome requires a "start low, go slow" approach. Always consult your nephrologist and ophthalmologist before beginning, as they can identify specific contraindications based on your current kidney function or visual field loss. A physical therapist experienced in rare genetic conditions can help create a customized plan that accounts for the unique skeletal morphology associated with Mainzer-Saldino syndrome.

How can I adapt to difficult days?

It is vital to practice pacing. If you experience increased fatigue—a common symptom in Mainzer-Saldino syndrome—reduce intensity or opt for restorative stretching instead of aerobic exercise. Listen to your body; if joint pain or excessive exhaustion occurs, prioritize rest to prevent secondary complications.
