Abstract:
OBJECTIVE:To explore the genetic basis for a girl with febrile convulsion as the main manifestation.
METHODS:The child was subjected to whole exome sequencing (WES) and copy number variation sequencing(CNV-seq). Fluorescence quantitative PCR was carried out to validate the microdeletion in her family.
RESULTS:The 7-year-old girl was diagnosed with febrile convulsion (complex type) for having fever for 3 days, mild cough and low thermal convulsion once. Her father, mother and aunt also had a history of febrile convulsion. A heterozygous deletion with a size of approximately 1.5 Mb was detected in the 16p13.11 region by WES and CNV-seq. The deletion has derived from her father and was confirmed by fluorescence quantitative PCR.
CONCLUSION:16p13.11 microdeletion syndrome has significant clinical heterogeneity. Different from those with epilepsy, mental retardation, autism, multiple malformations, carriers of 16p13.11 deletion may only manifest with febrile convulsion. Deletion of certain gene(s) from the region may be related to febrile convulsion and underlay the symptom of this child.
