ABSTRACT
OBJECTIVE@#To analyze the clinical phenotype and genetic characteristics of a child with Perlman syndrome.@*METHODS@#Genomic DNA was extracted from peripheral blood samples from the patient and her parents. Whole exome sequencing (WES) was carried out to detect potential variant in the proband. Candidate variant was verified by Sanger sequencing. The pathogenicity of candidate variants was evaluated according to the guidelines of the American College of Medical Genetics and Genomics (ACMG).@*RESULTS@#The results of WES showed that the proband has harbored compound heterozygous variants of the DIS3L2 gene, namely c.2109delC and c.1829.c.1830insC, which were respectively inherited from her mother and father. The results were confirmed by Sanger sequencing. Based on the ACMG guidelines, the two novel variants were both predicted to be pathogenic (PVS1+PS2+PM2).@*CONCLUSION@#The compound heterozygous variants of the DIS3L2 gene probably underlay the Perlman syndrome in this patient. Above finding has enriched the spectrum of DIS3L2 gene mutations.
