Abstract:
OBJECTIVE:To explore the genetic basis for a child affected with cerebral creatine deficiency syndrome 1 (CCDS1).
METHODS:High-throughput sequencing was carried out to screen pathogenic variant associated with the clinical phenotype of the proband. The candidate variant was verified by Sanger sequencing.
RESULTS:High-throughput sequencing revealed that the proband has carried heterozygous c.327delG variant of the SLC6A8 gene, which was verified by Sanger sequencing.Neither parent was found to carry the same variant.
CONCLUSION:The de novo heterozygous c.327delG variant of the SLC6A8 gene probably underlay the CCDS1 in this child.
