- Summary:
- A new study describes a new pediatric mitochondrial syndrome and discovery of the responsible gene, called CLPB. Researchers report findings based on gene mapping and exome sequencing in five children with CLPB-related disease. These patients had strikingly similar clinical findings including cataracts, severe psychomotor regression during febrile episodes, epilepsy, neutropenia with frequent infections, urinary excretion of 3-methylglutaconic aciduria, and death in early childhood.

A new study published in the American Journal of Human Genetics demonstrates the continued important contributions from the Center for Pediatric Genomic Medicine at Children's Mercy Hospital in Kansas City, Mo. The study describes a new pediatric mitochondrial syndrome and discovery of the responsible gene, called CLPB. Dr. Carol Saunders and her team partnered with collaborators in Denmark to report their collective findings based on gene mapping and exome sequencing in five children with CLPB-related disease. These patients had strikingly similar clinical findings including cataracts, severe psychomotor regression during febrile episodes, epilepsy, neutropenia with frequent infections, urinary excretion of 3-methylglutaconic aciduria, and death in early childhood.
"This research once again highlights the power of genomic medicine in the diagnosis and discovery of rare pediatric conditions," said Saunders, clinical laboratory director of the Center for Pediatric Genomic Medicine "In this case, we have identified one of the many genes, CLPB, involved in mitochondrial diseases. These findings emphasize the importance of basic research into the characterization of human CPLB gene function and will pave the way for the diagnosis of other patients."
