ABSTRACT
OBJECTIVE@#To analyze the clinical and genetic characteristics of a child with clinical manifestations of hypoplasia, epilepsy and abnormal face.@*METHODS@#The clinical data of the child were collected. The peripheral blood samples of the patient and his parents were extracted for high-throughput sequencing, and Sanger sequencing verification and bioinformatics analysis were performed to detect suspected pathogenic variants.@*RESULTS@#The clinical manifestations of the child were overall developmental backwardness, seizures, autism, and special facial appearance. High throughput sequencing showed that there was a heterozygous mutation of exon 11 c.1920_c.1927delCCTCTACC (p.Ser641Rfs*31) of the DYRK1A gene. The same variant was found in neither of her parents, suggesting that it has a denovo origin.@*CONCLUSION@#The exon11 c.1920_c.1927delCCTCTACC (p.Ser641Rfs*31) mutation in DYRK1A gene was the genetic etiology of the case, which enriches the pathogenic gene spectrum of DYRK1A and provides the basis for clinical diagnosis and genetic counseling.
