Researchers at the Icahn School of Medicine in New York have identified a previously unknown recessive neurodevelopmental disorder that appears to be the most common of its kind ever discovered. The condition, which affects brain and nervous system development, is caused by a specific genetic mutation and can lead to intellectual disability, seizures, and other neurological symptoms.

Why it matters

This discovery represents a major breakthrough in understanding rare genetic disorders and could pave the way for new diagnostic tools and potential treatments for affected individuals and families. Identifying the genetic basis of this condition is an important step toward improving outcomes for those living with neurodevelopmental challenges.

The details

The research team, led by Dr. Alicia Montoya, analyzed genetic data from thousands of patients and identified a specific mutation in the ABCD1 gene as the cause of this newly described neurodevelopmental disorder. Further studies are underway to fully characterize the condition's symptoms, prevalence, and long-term prognosis.

  • The research was conducted over the past 3 years at the Icahn School of Medicine.
  • The findings were published on March 30, 2026 in the journal Nature Genetics.
