Pediatric X-linked adrenoleukodystrophy: phenotypes, variants, and HSCT outcomes
Early stem cell transplants in infancy dramatically improve survival for children with adrenoleukodystrophy, emphasizing the urgent need for newborn screening programs.
A Chinese pediatric ALD cohort (n=31) expands the ABCD1 mutation spectrum with 3 novel pathogenic variants and reinforces that early HSCT (Loes score <9) confers clinically meaningful survival advantage (78% vs 29% 5-year OS). Substantial diagnostic delays identified in this cohort highlight the urgent need for newborn screening programs to capture patients within the optimal therapeutic window.
