Analysis of the mitochondrial genome in sudden infant death syndrome

Acta Paediatr. 2003;92(3):386-8. doi: 10.1080/08035250310009338.

Abstract

Aim: To investigate the mitochondrial genome and its association with sudden infant death syndrome (SIDS).

Methods: Twenty SIDS infants were screened for previously reported mitochondrial DNA mutations using direct sequencing. The whole mitochondrial genome was also sequenced for six of the infants.

Results: Three substitutions, A11467G, A12308G and G12372A, comprising a haplogroup were present in four infants diagnosed as pure SIDS. This haplogroup was also common in a control group.

Conclusions: No specific mutation or polymorphism was found in association with SIDS.
