: Cardiac monitoring after gene therapy is critical in patients with Duchenne muscular dystrophy, according to a presentation by Beth Kaufman, MD.

Dr. Kaufman, director of the pediatric cardiomyopathy program at Stanford Medicine Children’s Health in California, noted that patients with DMD often experience cardiomyopathy and can be susceptible to systemic inflammation, leading to heart failure. Myocarditis is often an adverse event in gene therapy so extra caution is warranted.

The Muscular Dystrophy Association continues to advocate for improved air travel accessibility for wheelchair users, as highlighted by Paul Melmeyer, executive vice president of public policy and advocacy at MDA, during the 2025 .

“Working with the DOT, we were also able to . . . promulgate some rules that protect the safety and dignity of those who are wheelchair users in air travel—one of the most currently inaccessible experiences that . . . wheelchair users experience,” Melmeyer said.

⭐ This rule includes several provisions, such as:

- Safe and dignified assistance for individuals requiring accommodations.

- Assistance with boarding, deplaning, connecting flights and airport navigation.

- Return of wheelchairs and assistive devices in the same condition they were received.

- Transportation of delayed wheelchairs or scooters to the passenger’s final destination within 24 hours, along with reimbursement for related transportation costs.

- Replacement or repair of damaged wheelchairs or scooters, with airlines covering costs for loaner wheelchairs.

Differences in treatment and health care costs for Duchenne muscular dystrophy exist among racial and ethnic groups.

White patients had the highest health care expenses, averaging $108,895 annually, compared with $59,501 for Black patients, $61,199 for Hispanic patients, and $65,247 for those of other or unknown backgrounds. Researchers suggest that these differences were largely driven by higher use of exon-skipping therapies among White patients, a costly but effective treatment for certain genetic mutations in DMD.

👋 Meet our newest patient perspective contributor, Sarka Palouckova! Sarka is the grandmother of William, who has Duchenne muscular dystrophy (DMD).

In her first column for Rare Disease Advisor, she writes:

“William was born a healthy, hefty baby. He was quieter than most newborns—a calm presence in our lives. As he grew, we started to notice small differences. He never crawled, skipping that milestone entirely. Instead, he went straight to walking—though it took him 14 months to take his first steps.

A few days later, we saw something unusual—he was walking on his tiptoes. At first, we thought it was just a phase, something he would grow out of. But as time passed, we noticed more.

After many doctor visits, including with orthopedic specialists, William’s family still felt that 'something didn’t feel right.'"
