Clinical characterization and genetic testing for a patient with creatine deficiency syndrome 1 / 中华医学遗传学杂志

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.
