ABSTRACT
OBJECTIVE@#To analyze the clinical phenotype and pathogenic variant in a child diagnosed with mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH).@*METHODS@#Clinical phenotype of the child was reviewed. Whole exome sequencing was carried out for the child. Candidate variant was verified by Sanger sequencing of the family member.@*RESULTS@#The proband manifested dyskinesia, development delay, cerebellar hypoplasia and bilateral hearing impairment. WES results revealed that the proband has carried a pathogenic c.1641_1644delACAA (p.Thr548Trpfs*69) variant of the CASK gene, which was verified by Sanger sequencing to be a de novo variant.@*CONCLUSION@#The c.1641_1644delACAA (p.Thr548Trpfs*69) variant of the CASK gene probably underlay the MICPCH in the proband. Above finding has provided a basis for genetic counseling. WES should be considered for the diagnosis of neurological dysplasia.
