Summary
Genetic testing identified new causes of neonatal encephalopathy (NE), aiding early diagnosis and treatment. This study expands the known genetic variants linked to NE, improving molecular diagnostic capabilities for affected newborns.
Area of Science:
- Genetics
- Neurology
- Molecular Biology
Background:
- Neonatal encephalopathy (NE) has a complex genetic basis.
- Early diagnosis of NE is crucial for effective therapeutic strategies.
Purpose of the Study:
- To identify novel genetic variants associated with neonatal encephalopathy.
- To expand the mutation spectrum for genes implicated in NE.
- To provide new evidence for molecular diagnosis of NE.
Main Methods:
- Clinical evaluation of NE patients with unclear etiology.
- Utilized ammonia testing, metabolic screening, aEEG monitoring, and MRI.
- Performed genetic testing and in-silico protein structure prediction (Dynamut2, RoseTTAFold).
Main Results:
- Identified 15 new pathogenic variants in 12 genes among 113 NE patients.
- Seizures were the primary initial symptom in this cohort.
- Seven novel variants predicted premature translation termination; four affected KCNQ2 protein structure.
Conclusions:
- The study broadens the spectrum of known NE-associated gene mutations.
- Presents new molecular diagnostic evidence for neonatal illness.
