Unexplained neonatal encephalopathy: potential role of methylenetetrahydrofolate reductase polymorphisms.

Scalais E, Larcher M-E, Nuttin C, Gijzels C, Mataigne F, Weinacht M, De Meirleir L., Luxembourg and Brussels, Belgium.

Background: Methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms are associated with lower MTHFR activity.

Objective: retrospective case-control evaluation of unexplained neonatal encephalopathy with reference to both C677T and A1298C as a genetic risk for this condition.

Method: Seven infants with unexplained encephalopathy, 42 healthy individuals and 7 infants with genetic disease were genotyped for MTHFR polymorphisms (C677T, A1298C). All studied infants had metabolic screening, early magnetic resonance imaging (MRI) and were followed between 6 months and 3 years.

Results:

Conclusion: The data presented here suggest that MTHFR polymorphisms play a potential role in unexplained neonatal encephalopathy.
