Danielsson A, et al. - In this case series of children with benign paroxysmal torticollis of infancy (BPTI) diagnosed between 1998 to 2005 at Astrid Lindgren Children's Hospital, Stockholm, Sweden, researchers described the natural course of benign paroxysmal torticollis, how this disorder is associated with migraine and other paroxysmal diseases, and to examine candidate genes. From 2005 to 2007, a neurological examination and a formalized motor assessment were performed. Results revealed that rare genetic variants in CACNA1A and ATP1A2 were found in two children. It was observed that BPTI was transient and did not lead to neurological sequelae. Data reported that most children who were afflicted experienced either a mild migraine or no paroxysmal disorder at all in their adolescence. According to the findings obtained, genetic variants in candidate genes were few, showing potential genetic heterogeneity.
